Cleanliness and proper hygiene are something many of us grew up learning. It teaches us how to keep ourselves safe and healthy, along with proper etiquette and sanitation. You don’t want to go outside looking dirty and unkempt if you want people to take you seriously.
However, you’ll be surprised to know that many celebrities you might look up to don’t follow proper hygiene. So if you’re interested in finding out which ones, we hope you won’t regret checking out the list below.
Cameron Diaz
Cameron Diaz is a well-known actress, and hearing about someone like her having unhygienic traits may be something that shocks everyone who knows her. She has particular beliefs regarding hygienic products, which are the opposite of what they are made for.
She believes that using deodorant keeps your body odor intact, which she uses as an excuse to condone deodorant. For this reason, she forgoes deodorant use, and sadly, everyone around her has had to put up with it.
Marilyn Monroe
According to the 2007 autobiography of Clark Gable, despite being one of the most famous stars of her time, Marilyn had her fair share of undesirable traits. She was described to be flatulent, dirty, and also had a habit of eating in bed.
Eating in bed, while messy, is something everyone does once in a while, but the actress would shove her plates under her bed sheets before sleeping. She would even forgo regular showers or bathing and opted to go without underwear.
Mila Kunis
Mila Kunis is one of the most beautiful women in Hollywood, but her hygiene practices don't make her seem as so. These practices are shared by her husband, Ashton Kutcher, who also follows a similar lifestyle of cleanliness or uncleanliness.
She revealed that growing up without hot water, she wouldn't shower much, and this habit remained as she grew. The actress would also avoid using soap on her body regularly, cleaning only the important parts.
Jake Gyllenhaal
There are few out there that don't enjoy Jake Gyllenhaal as an actor, but we can't speak the same praises regarding his beliefs on cleanliness. The actor practices hygiene traits that are questionable to anyone who hears about them, and we're all a little weirded out.
In a Vanity Fair interview, the actor said he believes that it is not necessary for people to take regular showers as the body cleans itself. He believes less frequent showers to be better for the maintenance of his body, and we're not sure where he got his information from.
Shia LaBeouf
For his role in the 2014 movie "Fury", Shia decided to go all the way to portray his character in the movie. The character he was portraying was going through the deprivations of war, and so to create that effect Shia refused to shower for weeks on end.
He reeked so badly that apparently, it was too much for other cast members to handle, and they moved him to a different lodging away from the others. Shia has not denied any claims so all we have is the words of his colleagues.
Anderson Cooper
This guy looks like he dresses well for a living, so there can't be a reason why he'd have anything that makes him too undesirable, right? Well, it would seem like you can't judge appearances based on pictures alone because it's a different story in real life.
When working, Anderson is known to put on a pair of jeans, but the problem arises from whether he washes them or not. He would wear a pair of jeans daily to work and only wash them three or four times a year.
Russell Crowe
There aren't many actors out there who can boast the same number of years Russell Crowe spent as an actor. Through the years, he has built up a specific reputation for himself with his many movies and projects, and now he seems to have a new rep of the unhygienic kind.
Due to a habit of sweating too much, Russell has been said to be surrounded by a body odor that keeps people away from interacting with him. During award shows, fellow actors have been said to stand downwind to avoid the smell.
Matthew McConaughey
Matthew is an actor best known for his roles in many romantic comedy films, such as "How to Lose a Guy in 10 Days" and "The Wedding Planner". He is also known for being one of the most handsome actors in Hollywood, but despite this, he has problems with hygiene.
The actor has been known to emit a body odor that reeks of underarm sweat. Despite this, he refuses to put on deodorant or antiperspirant.
Uma Thurman
Uma Thurman is a legendary actress, and although news about the actress and her movies has died down over the years, the topic of her hygiene still remains. The actress had been revealed to wear old clothes covered in food stains.
A stylist who was working with Uma Thurman at one point revealed the issues regarding her hygiene and said she peeled shrimp off her back. Shrimp peeled off an old crusty t-shirt definitely doesn't sound appetizing at all.
Miley Cyrus
Miley Cyrus is a singer and actress many of us have grown up with, from her Disney days to becoming a famous star. Currently, she is a Hollywood star with a career that is as wild as her personality.
It would seem her personality is where her wildness stops as the star has been known not to use deodorant that isn't organic in nature. Experts who have seen her tongue from pictures have also said it looks unhealthy with a fungus-like growth.
Leonardo DiCaprio
Despite being one of the most successful, talented, and popular actors out there, even Leo couldn't escape the bad hygiene trap. Leonardo wanted to limit his carbon footprint as an environmental activist, but that somehow resulted in bad hygiene.
The actor believes deodorant is bad for the environment and doesn't wear any, along with telling others not to use deodorant either. He also showers twice a week because he believes using less water will help to conserve more water.
Joey Essex
Joey Essex has a nasty habit of teeth picking that we are all familiar with, except he makes it more disgusting. People usually clean their teeth to clear them out of annoying food that is stuck, and in the end, we wipe our hands or wash them.
On the other hand, the TOWIE star uses his fingers to pick out food, and instead of flicking it, he smells the small pieces of food. We aren't sure how he doesn't keep himself from puking every time the nasty smell of spit-covered food touches his nose.
Joan Rivers
We don't know what celebrities have against deodorant, but many people on this list can't seem to stand using it. Even though she is no longer with us, with Joan it was never an exception. The only difference here is that Joan found a different way to cover her body odor and mask it from those around her.
You wouldn't expect to hear this, but Joan believed that sprinkling clothes with water and vodka are way more effective than your usual deodorant. The only thing you'll accomplish with this is making others think you're drunk because you'll always smell like alcohol.
Gwyneth Paltrow
Gwenyth Paltrow is a name you may not be surprised to see on a list like this because of her lifestyle brand, which has her try out very weird things. Some of the things she's tested out have often had the effect of driving anyone nearby away.
During a Met Gala appearance, Paltrow tried out a new deodorant, which was nasal torture for her fellow celebrities. She opted for a scent with no aluminum, which she believed was harmful, but instead turned out stinky.
Jessica Simpson
Since we were kids, we have been taught to brush our teeth twice daily to maintain proper dental hygiene. On the other hand, Jessica Simpson has opened up about her lack of dental hygiene and made numerous statements throughout the year regarding her teeth.
The actress reportedly doesn't brush her teeth twice a day or even once, and the most she has brushed her teeth is twice a week. She has said that all she uses is Listerine and sometimes her sweater to wipe her teeth.
Brad Pitt
Brad Pitt is one of the actors who is always at the top of the A list of celebrities in Hollywood so we always expect the most from actors like him. Celebrities like this guy have a hard time fitting in a time for a shower with their busy schedule, but how hard can it be for a 5 minute shower?
Brad only showers when he gets the chance to, and if he can't find the time, the actor will instead use baby wipes. Despite his efforts, the stench from not showering is still prevalent in the air around him.
Post Malone
Post Malone is a rapper who looks like a pretty nice guy who you wouldn't mind hugging. That isn't the same for others who don't like his raggedy and rough appearance, which may rub some people the wrong way.
Despite his smell not appealing to others, the rapper has had no qualms with others' issues about his lack of deodorant usage. He revealed that his musk is natural and that if you didn't like it, then it's not for you, making it sound more like a "you" problem.
Charlotte Crosby
After spending the night drinking at the Celebrity Big Brother house, Crosby wetted her bed because she couldn't get to the bathroom. According to sources, this was a recurring problem for Charlotte as it had happened before.
Charlotte's bed was also reported to be covered in urine and food stains most of the time. Remains of a half-eaten turkey sandwich were present, along with tanning product smudges on the dirty bed sheets.
Eva Mendez
Nail-biting is a dirty habit as it is annoying for both you and people close by watching you. We can't help doing it under stress or when we're nervous, and sadly there are a lot of things around to get on our nerves.
Eva Mendez also suffers from excessive nail-biting, which you should avoid because your mouth is coming into contact with undesirables. You aren't always aware of what your hand touches and don't want the dirt under your nails getting into your mouth.
Shailene Woodley
We're not sure how the actress concluded that eating something akin to dirt would be good for your body and health. Besides using oil pulling to maintain her dental hygiene, the actress has also been known to consume clay.
You heard it right! Woodley has revealed in an essay for Into The Gloss that consuming clay is good for your teeth and insides. She warns us to check your clay source, although we're sure we won't be having clay for dinner anytime soon.
Angelina Jolie
Couples that stink together seem well together because Brad wasn't the only one with rumors regarding his dirty hygiene. We don't know if it's because of how many kids she's looking after, which does sound like a good enough excuse.
Taking care of her kids keeps her busy enough, which is why she often goes an entire week without taking a bath or washing her hair. Sources have also claimed that the kids have also picked up their parents' habits, with both parents taking no action against it.
Kelly Clarkson
Celebrities have been known to put on new clothes almost daily, so to hear someone like Kelly Clarkson saying she goes commando all the time is weird. The singer reportedly skipped underwear during all her appearances on "American Idol".
Suppose our private parts are coming into contact with new clothes which have been dipped in who knows what type of chemical, then underwear is a must. The last thing you want is to catch something that's going to give you a rash because you went commando.
Mel Gibson
Mel Gibson is an all-around good guy with specs that will leave many other actors burning with jealousy. There is one thing that we can think about that won't leave others green with envy and that's his apparent unhygienic quality.
People and actors who have previously worked with Gibson have stated that the actor gives off a smell of sweat and cigarettes. He also showers less frequently, usually once every few days, and doesn't use any deodorant.
Katy Perry
Katy Perry is pretty open about her unhygienic traits, but she also doesn't give much stock to what others have to say or think about them. She's always bouncing and jumping during her performances which she says has made her more flatulent.
It seems a bit too much to share for an interview, but at least we found out what Katy and Orlando (also featured here) had in common in their relationship. Unhygienic traits have become common in many celebrity couples, and it seems these two also fall into the same category.
Kim Kardashian
Unlike other celebrities on this list, Kim stays clean by showering regularly and washing her hair twice a week. Showering and washing hair alone can't tell you enough about someone's hygiene practices, as you'll find out with Kim.
Most people will tell you that you should remove your makeup before going to bed because it'll get on your sheets and pillows and cause acne. Kim, on the other hand, believes in sleeping with makeup on because she's too busy to do it in the morning.
Kate Upton
Biting nails is more common than you'd expect, and Kate Upton is no stranger to this familiar and problematic habit. She chows down on her manicured nails regularly, and because of this, they always look shorter.
This has led to her not being able to try different colors of nail polish for her nails, and she has had to settle for a nude polish instead. The nude also makes the added effect of making her nails look bigger because of how short they get from excessive biting.
Harry Connick Jr.
Nail-biting usually stems from being nervous or anxious in a situation you feel uncomfortable. Harry Connick Jr. took nail-biting to a new level, making it more disgusting for us even to hear.
This is something we wish we could forget, but Harry revealed on The Todd and Erin Morning Show that he bites off his toenails too. He discussed it further, saying he doesn't require toenail clippers as he can bite his toenails off and chew them.
Jennifer Aniston
Despite being in her 50s, the Friends star still can make guys go crazy about her wherever she goes. It would seem now that her looks aren't the only thing making people grow crazy, as her hygiene is just as effective of a weapon.
Jennifer has reportedly been known to have a breath that stinks of coffee, making it hard for actors to perform in kissing scenes with her. Drinking so much coffee that it affects your breath definitely isn't a good sign of oral health.
Courteney Cox
Courtney Cox has appeared in movies after her time in Friends, but it remains her most successful project. Her character of Monica, who is a clean freak with OCD regarding her apartment, is apparently something that doesn't translate to the real world.
She has been said to give off a sweaty musk due to her forgoing the use of any type of deodorant. This was revealed by her ex-husband, David Arquette, who said his then-wife didn't pay any attention to how she smelled to other people.
Emily Ratajkowski
Emily told Jimmy Kimmel in 2017 about an eight-year period in her life where she would haul around a car which she described as a literal garbage dump. According to the celebrity, there were all kinds of garbage, from records to tampons.
A clean car is a sign that you know how to take care of yourself and maintain cleanliness, so for someone like Ratajkowski to drive a dump is surprising. She later revealed that she got rid of the car to take her cleanliness seriously.
Kesha
One of the biggest pop stars of the early 2000s, Kesha, is someone with unhygienic traits that she is unafraid to talk about in public. The singer has been criticized for stinking up the place wherever she goes, but the complaints have zero effect.
She also participated in the disgusting drinking habit, which you should avoid if your name isn't Bear Grylls. The singer may have moved past her unique drinking habits, but we can't say the same for her odor.
Alicia Silverstone
Best known for her role as Cher Horowitz in "Clueless", Alicia doesn't seem to follow a clean lifestyle that would leave her character proud. When on set, she was known for her hygienic issues, with the problem laying in how bad she smelled.
Like many others on this list, Alicia stays away from deodorant, which is regretful for the people around her. The most disgusting thing is how she feeds her child like a bird by chewing food and spitting it in her child's mouth.
Adele
Adele might be the only celebrity on this list with unhygienic traits that is unique from other celebrities. The singer has a bad habit of picking her nose and isn't closed off about it, too, as she revealed in an interview with The Sun.
Things just don't stop here as she doesn't just enjoy digging into her nose and rolling boogers between her fingers but also the boogers of her son. She'll roll them between her fingers into a ball and then flick them in whichever direction she wants.
Vanessa Paradis
One of Johnny Depp's partners, Vanessa, complained about the actor not showering or washing his hair. In a hypocritical turn, Vanessa has now fallen into the limelight as someone who is also unhygienic.
The model and actress would spend days without touching any water, leaving her with a strong and musty body odor. This led to many of her friends and family avoiding her because of how bad the stench was attacking their sensitive nostrils.
Naya Rivera
When you imagine Naya Rivera, the picture that comes to mind is her persona in Glee, wearing a cheerleader outfit and singing on stage. That all changed for her fans after an interview she had in 2015.
After a question about her personal hygiene, Naya revealed that she would go weeks without touching her shower. This shocked many of her loyal fans, who thought the star couldn't get as bad as she got. In 2020 Naya passed away under mysterious circumstances.
Josh Hutcherson
We all have some traits that come out when we're distracted or not thinking, with the traits being normal or weird at most. "The Hunger Games" star had a nasty habit that had his co-stars recoiling in disgust and darting away from him.
He would apparently blow spit bubbles when he was in a long thinking process, and it got pretty annoying for others around him. Just imagine standing in front of him, prepping for a kissing scene, and he starts spitting bubbles at you.
Dax Shepherd
Dax follows a lifestyle where he only showers when he feels too dirty. According to himself, Dax is more unhygienic than Kristen herself, as she has to wash more frequently to get rid of her makeup.
He also bathes his kids together with himself using the same water as he believes it is his responsibility to save the environment. Dax probably knows how bad his hygiene had gotten in the end as he revealed that his hygiene could always be better
Orlando Bloom
Orlando Bloom made his mark in Hollywood with his appearance in the "Pirates of the Caribbean" films. His hygiene seems to have also made its mark amongst his fans for the wrong reasons.
During his marriage to Miranda Kerr, the actress had many problems with her husband stemming from his uncleanliness and hygiene. He would wear the same clothes for weeks without washing them, even when they got too smelly.
Ashton Kutcher
This actor has some controversial thoughts about staying clean. He says that if he feels dirty and wants to get clean, there's always a bar of soap nearby that is ready to get the job done. He doesn't say how often that happens, though.
His frequent disregard for taking showers has also rubbed into his children, and we can't say whether the kids like it or not. Ashton believes there's no point in bathing your children if you don't see any dirt on them... Umm, Ash, just because you don't see dirt doesn't mean it's not there.
Robert Pattinson
Robert is an actor who has the world divided in how they view him, with one side seeing him as Edward from twilight while the others see him for his other serious films. Despite this split, everyone seems to have a common ground regarding the issue of Pattinson's hygiene traits.
According to the actor himself, during his Twilight days, it was rare for him to get up and shower and wash his hair. Pattinson revealed that the longest he went without washing his hair was a total of six weeks.
Maria Bakalova
To get in character to play the role of Borat's daughter, Maria had been asked to stop practicing her hygiene by the production team. This is because the character she was portraying had been known to have a body odor emitting from her.
At the time, it was not possible for Maria to go through with her unhygienic process as she was already filming another movie. To remedy this, she made her own body odor by mixing banana peels, old eggs, vinegar, old olive oil, and onions.
Bradley Cooper
Bradley Cooper is an actor who looks well put together in life, so seeing his name on a list of unhygienic celebrities may be a bit surprising for most. Unlike other celebrities, Bradley doesn't have as huge of a problem with staying unhygienic.
Despite showering regularly and keeping himself clean, the actor has been said to give off body odor, which concerns the people around him. Despite this odor, Bradley refuses to use any sort of deodorant to cover up the musty smell of sweat.
Kristen Bell
Celebrities who don't wash up regularly are more frequent than you'd expect, and you'd be shocked to hear what Kristen Bell and Dax Shepherd have to say about it. It would seem that these two stay away from showering or washing their hair on a daily basis.
They even allow their children to follow in their lifestyle by letting them have rare showers. They'll wait a while, and the minute they notice a stink coming from their kids is when they force them to shower.
Britney Spears
Britney Spears is a pop singer who can't seem to escape the light of controversy wherever she goes. Most of her problems arise from her more questionable behavior during the early days of her career, but now we're discussing her hygiene.
Britney has been known to skip out on regular showers and not use any deodorant. The smell got so bad to a point where even her bodyguard decided to sue her because he couldn't handle the stench given off from her body.
Kourtney Kardashian
Kourtney Kardashian has made a lot of money through her name, which she used to get a big house with a huge bath. With money like hers, you'd expect her to hit the spa every week to keep herself clean or to shower at home, but all is not as expected.
We don't know about her skipping out on any showers, but we can't deny anything about her not using any deodorant. It reached a point where her kids couldn't stand the stench just because she believed deodorant would be detrimental to her health.
Harry Styles
The British singer has come a long way from his One Direction days and ever since his decision to go solo. We can't deny the success he's gained. He's made his mark in Hollywood history, and it would seem he had also made his mark in staying unhygienic.
His former One Direction bandmates have made some choice of words regarding his stinky feet and smelly burps. Even Taylor Swift, his ex, has come out with statements regarding his smelly breath.
Ozzy Osbourne
Ozzy Osbourne has a long list of dirty habits that we're sure any other partner wouldn't be able to stand, but somehow his wife is able to. It speaks a lot about her patience if she's had to deal with this for years on end with no regrets and still loves him.
He apparently snores, farts, and sprinkles his urine on the toilet seat, which is pretty disgusting. Now, the first two can be excused because they're natural occurrences in your body, but the last one can easily be fixed by aiming inside the toilet bowl.
Christina Aguilera
One of the highest-rated pop stars, she started her career as a young star before transitioning into a more adult image. Besides being a star, she is also a businesswoman with her own line of scents and perfumes, but her dirty habits remain despite the rumors about her.
Her friends and others who know her have provided statements regarding the singer, saying she smells like hot dogs most of the time. There was another statement saying she smelled like a 12-year-old girl's bedroom.
Jennifer Lawrence
This is according to actor Liam Hemsworth, but before a kissing scene he shared with Jennifer Lawrence, the actress would apparently practice bad dental hygiene. The bad smell had made it pretty uncomfortable for Liam to carry on with the actual kiss.
Before shooting a scene, the actress would snack on some garlic and oftentimes tuna to get her breath to stink. She wouldn't even brush her teeth after snacking; it just sounds like a prank between two friends.
Zac Efron
The High School Musical star has come a long way from his musical days with Disney with movies such as "Baywatch". He looks like someone who takes proper care of himself, especially his appearance, but don't be fooled as everything isn't as it seems.
The actor spends a lot of time in the gym, as we can see from the results in the body, but too much time at the gym means excessive sweating. He wouldn't shower for weeks after a workout and use wet wipes instead to save time.
Viggo Mortensen
The "Lord of the Rings" star is famous for the effort he puts into his characters when acting out his roles. It would seem that he takes things too seriously as he would often ignore his hygiene to immerse himself into his character.
During his days leading up to LOTR, the actor would go into the woods and live there to prepare himself. Staying away from civilization for so long, when he'd return, it was noted that he'd always come back smelling like the outdoors. And not in a good way.
Snooki
It seems like the number of life hacks that people have figured out just keeps rising, and as you expected, this one is just as weird. Snooki has reportedly found another use for cat litter besides using it as something for cats to do their business in.
The star has somehow come up with the idea that cat litter can be used to make a mask, a facial mask, to be honest. We can see how cat litter can be used to keep your house odor-free from cat poop, but we're not too sure about using it to clean your face.
Paget Brewster
Nail-biting can start as a small habit and grow into an annoying one you can't get rid of. Your fingers are in constant contact with many things usually covered in germs and bacteria too little for the eye to see.
Biting your nails can also be damaging to your fingers and nails, and this is a habit that Paget Brewster apparently suffers from. She last revealed in 2015 that her nail-biting habit was something she was trying to get past and forget.
Johnny Depp
Johnny is one of the most desirable actors ever to hit the big screen, and there's no doubt about the amount of money he's brought to Hollywood with his flicks. Recent events have made it hard for him, but the actor has finally moved past his issues.
His issues and worries might be a big reason why he goes on for days without taking a shower or washing his hair. This has been a long-lasting problem as apparently, his past partners have spoken up about it.
Avril Lavigne
Avril has had an unruly habit that comes out whenever she has had to deal with unnecessary attention from the paparazzi. We're not saying the paparazzi don't deserve it but spitting at other people sounds as unhygienic as it looks.
This was back in 2007 when she was caught making out with Deryck Whibley and spat at the cameras in annoyance. Later that year, in an interview, she revealed that she had been spitting at the paparazzi for over two years and didn't get what the big deal was.
Taylor Swift
Most fans of the tall blonde singer definitely weren't expecting her to show up on this list, but you don't always get what you want. Taylor still showers daily, but the only body part she washes is her upper body.
According to an interview with Ellen, she avoids washing her legs because she believes shaving her legs is enough work to keep them clean with water doing the rest. Even if you're shaving, you should still wash your legs with soap to get rid of all the dirt.
Julia Roberts
Julia Roberts is an actor who always looks picture perfect, without a hair out of place and a smile that is always ready for a camera. If that was actually true, then she wouldn't have made it onto this list now, would she?
She has concerns about the environment that are similar to fellow actor Leonardo DiCaprio and believes in the act of using less water to save more water. As a result, she rarely showers or bathes and stays away from using deodorant to hide bad odors.
Megan Fox
Known for her roles in the "Transformers" franchise, Megan fox is one of the most beautiful actresses around. She recently made it into the news after getting together with rapper MGK, which has resulted in many controversial topics.
Megan still showers daily, but her unhygienic traits stem from an awkward condition of forgetting important things, like forgetting to flush the toilet. This leaves a surprise for the next person to use the toilet, one they regret seeing.
Charlize Theron
The star revealed in an interview for David Letterman that she enjoyed being spoiled by the things her money could buy for her. This doesn't mean she avoids getting dirty as she regularly goes camping and travels around.
All this traveling and moving around is definitely going to get anyone dirty, but Charlize doesn't let the uncleanliness bother her too much. According to Charlize herself, she could go a week without showering or cleaning herself, and she wouldn't mind a bit.
Kristen Stewart
Kristen Stewart is an actress with whom many seem to have a problem due to how cold she looks most of the time. Right now, there seems to be a new source for why people can't stand her, and it seems that it stems from her habit of not taking showers regularly.
It was the same issue during her Twilight days, and she was revealed to go weeks without washing her hair and brushing her teeth. It got to a point where Robert Pattinson, another unhygienic celebrity, started complaining.
