Be warned, this article might make you feel a bit queasy! In the list below, we’ve explored 25 celebrities who have the grossest habits you’ve ever heard, and some of them are truly astounding…

Scroll down to find out which actor has publicly admitted to biting his own toenails, which singer can’t seem to put a lid on her spitting habit, and just how many people in Hollywood aren’t showering. Yep, celebrities can be just as gross as the ordinary human being, we’re just not sure why they felt the need to share these things with the world’s media.

25. Brad Pitt

Brad Pitt’s legions of fans might not look at him the same way after reading this, but it turns out that the last name ‘Pitt’ is an apt nickname for him. That’s because rather than using soap or shower gel like most normal people, Brad opts to keep his pits fresh with wet wipes.

The actor even passed this tip on to his Inglorious Basterds co-star, Eli Roth. Roth had been complaining that he didn’t have time to shower and Pitt quickly put him straight, saying “Baby wipes, man, baby wipes!”. Helpful tip or just spreading the grossness, you decide!

24. Megan Fox

Megan Fox is an international sex symbol with plenty of adoring fans, but her personal hygiene habits aren’t particularly glamorous. The actress and model stunned interviewers at FHM when she admitted that she has a very nasty bathroom routine. Be warned – it’s about to get graphic!

Despite her beauty and elegance, Fox has one unpleasant habit: she doesn’t flush the loo. Fox admitted this herself, saying: “I’m horrible to live with. I don’t clean. My clothes end up wherever I take them off. I forget to flush the toilet. Friends will tell me, ‘Megan, you totally pinched a loaf in my toilet and didn’t flush.'” Wow.

23. Johnny Depp

Johnny Depp’s suave stylishness seems to have been waning in recent years. The actor, producer and musician has been in everything from Alice in Wonderland to Pirates of the Caribbean and often plays bedraggled and unhygienic characters, maybe because of his real-life scruffiness.

He has bad breath. According to the National Enquirer, Angelina Jolie, co-starring with Depp on The Tourist, was unhappy with the actor’s cigarette breath. She requested that he rinse his mouth out with mouthwash on set and munch mints when he went out dining with herself and her husband, Brad Pitt. Poor Angelina.

22. Kesha

During Kesha’s early career, her persona was all about being brash and disgusting. She once proudly announced to Radio One: “I smell like a hobo. One time, someone told me I smelt like a shrimp on a diaper. I thought I could make a fragrance that was like a shrimp on a Faberge diaper but I don’t know if people want to smell like that.”

We can assure you they don’t, Kesha! In the very same interview, she also revealed that she once drank her own urine, apparently in an effort to be healthy? She explained: “I was told drinking my own pee was good. Somebody tried to take my pee away from me and I said, ‘That is mine!’ So I snatched it up and took a chug.”

21. Robert Pattinson

Heartthrob Robert Pattinson has a few dirty secrets. The English actor began his film career playing Cedric Diggory in Harry Potter but is best known for his role as Edward Cullen in Twilight, so it makes sense that his hygiene is worse than that of a 100-year-old vampire.

One of Edward’s most standout features is his perfectly coiffed hair, but it seems that it’s the result of a revolting habit. Pattison goes up to six weeks between washing his hair, saying “I don’t really see the point in washing your hair.” It’s a wonder he split up with ex-girlfriend Kristen Stewart since she also doesn’t wash her hair often.

20. Miley Cyrus

Plenty of magazines have run features about Miley Cyrus’ bad behaviour, but apparently drinking hard and wearing teeny tiny shorts at the VMAs aren’t the only things landing her in hot water. She has also garnered criticism from family and friends for living in a total pigsty.

According to Life and Style, Cyrus’s aversion to cleaning was enough to drive her boyfriend, Liam Hemsworth, crazy. Sources say that her house is filled with “dog poop and pee everywhere, old food, pizza boxes, takeout containers, fast-food wrappers and dirty dishes piled up.” Eww.

19. Julia Roberts

Julia Roberts is one of America’s sweethearts, having played the romantic lead in countless films. That’s why it’s so surprising that this refined lady apparently eschews deodorant completely, never applying any and attending red carpet events while embracing her natural scent. That’s nuts!

Roberts also avoids showering, at least according to her former bodyguard. She claims these choices are for environmental reasons, in order to save water and the Ozone layer. The question is: if she doesn’t use water, then how does she keep herself clean?

18. Britney Spears

Britney Spears might be the ultimate pop star, but she’s also got some less glamorous habits. Fernando Flores, Britney’s former bodyguard, filed a lawsuit against the singer in which he detailed her flatulence and heavy smoking “which made her smell continually of stale tobacco.”

He went on to say that she “broke wind or picked her nose… [not] self-consciously and unapologetically.” Spears has also admitted to a really bad nail-biting problem, often biting them until they bleed. She even showed off her bloody stumps on The X Factor in 2012. Yuck.

17. Christina Aguilera

Xtina is another superstar with a scent issue. According to Grouplove’s Hannah Hooper, Aguilera “smells like hot dogs”, while a reporter from Arena Magazine described her as smelling like “a 12-year-old girl’s bedroom on a school-disco night”.

What’s even more disturbing, however, is that Aguilera has been spotted using the bathroom and not washing her hands afterwards multiple times. Finally, there was the time she performed at Etta James’ funeral and people noticed something strange dripping down her leg. Gross!

16. Adele

At first glance, Adele seems like an elegant soul singer with impeccable taste. With that said, despite being one of the best-selling music artists of all time, she sure has some pretty horrible personal habits. The singer has a not-so-secret secret… she loves picking her nose.

If that isn’t gross enough, she also likes to seek out her son’s boogers. She once told The Sun: “I’d like to stop picking my nose. It’s a really bad habit that I have.” The good news is that Adele managed to quit smoking, so there’s a good chance she could quit picking too.

15. Katy Perry

Katy Perry has never shied away from being honest, even with things she probably shouldn’t confess. In a 2009 interview for Myspace, she told Florence Welch of Florence and the Machine fame, “I fart a lot. I’m hopping around. I’m a little gassy. I don’t care.” Nice!

Thanks for the over-share Katy! Luckily we’re guessing that her boyfriend Orlando Bloom doesn’t mind because he’s got plenty of bad habits of his own. Apparently, he doesn’t like to wash himself or his clothes, which really used to bug his ex-wife Miranda Kerr.

14. Harry Connick Jr.

This Harry Connick Jr fact is seriously gross, so much so that we wish we could erase this one from our memory! Harry Connick Jr. is a seriously talented guy: he can act, sing and he can play the piano. But the Will & Grace star also has another hidden talent that we really wish he hadn’t told us about.

Connick Jr. doesn’t just bite his fingernails, he also bites his toenails too. Ewwwwww! He admitted in a radio interview on The Todd and Erin Morning Show, saying: “I can chew my own toenails off. I’ve never needed clippers.” No wonder we’ve never seen him in sandals.

13. Alicia Silverstone

Is Alicia Silverstone secretly a bird? Because her feeding technique definitely reminded us of something from the Discovery Channel. In 2012, Silverstone admitted that she used a very special mouth-to-mouth feeding technique when her young son started weaning.

The actress uploaded a video to her personal website, in which she chewed up some food in her mouth before spitting it directly into her baby son’s mouth. No, we’re not kidding. Naturally, the video caused controversy online and many people obviously felt nauseous after seeing it

12. Jessica Simpson

On the red carpet, Jessica Simpson loves flashing a smile at the cameras. However, it turns out that her grin isn’t as attractive as it seems, as she only brushes her teeth three times a week, as confirmed by her on the Ellen DeGeneres Show way back in 2010.

Apparently, she hates the feeling of freshly-brushed teeth and said that her gnashers feel “too slippery”. She also regularly swaps a toothbrush for a T-shirt instead?! Speaking to Ellen, Jessica explained, “I don t brush them every day. I’ll use a shirt or something … I know it’s gross, but I always have fresh breath.”

11. Matthew McConaughey

Matthew McConaughey is a dreamy actor. However, the Oscar-winning actor is definitely not going to win any awards for cleanliness, given that he doesn’t use deodorant: “I don’t like to smell like someone or something else. If [my smell] starts to bother someone, I’ll take a shower.”

Actress Kate Hudson, who has starred opposite McConaughey in a number of films, cannot stand his odour and even once brought a stick of deodorant to set and begged him to use it. McConaughey stuck to his guns, saying that all the women in his life enjoy his natural musk. Are you sure?

10. Cameron Diaz

So what is Cameron’s dirty little secret? Like Brad Pitt and Orlando Bloom, Diaz is firmly a member of the ‘no-deodorant’ club! However, Cameron has another nasty habit that doesn’t seem to make any sense, unless she wants to save on laundry detergent.

Apparently, the actress regularly wears the same outfit for several days in a row. Then, rather than bothering to wash them, Diaz throws the clothes away rather than chucking them in the washing machine. What a waste of money!

9. Anderson Cooper

Anderson Cooper generally looks sleek and sophisticated on the red carpet, but it’s a different story away from the cameras. Back in 2016, Cooper admitted to having a very nasty habit live on his own show, namely wearing the same pair of jeans every day for six months.

Come on Anderson, that’s gross! It gets worse when you find out what exactly his method of cleaning clothes actually entails. Apparently, rather than using a washing machine, Anderson steps into the shower and rubs soap on them instead. Why? Just do your laundry!

8. Halle Berry

Halle Berry is an iconic Bond girl and sex symbol, but fans might not be able to erase this snippet of information from their memory! Berry has a very bad habit that would probably make you think twice about leaning in for a kiss with her, she bites the skin on her mouth.

She constantly uses her teeth to tear any dry skin from her lips and admitted to The Huffington Post in 2014 that she needs some special moisturiser to stop her from doing it: “Without something on there, I just chew them off. I need some sort of moisture there, whether it be a lip balm or lip colour.”

7. Josh Hutcherson

Josh Hutcherson is one of the stars of the hugely successful Hunger Games series. But he and his co-stars have some very bad habits that used to reveal themselves during filming. Jennifer Lawrence ratted him out to MTV a couple of years ago by revealing that Hutcherson can’t stop clicking his neck.

He also has a weird tendency to blow spit bubbles when he’s thinking, something that his co-stars find hugely annoying. But Lawrence can’t complain too much, as she used to eat mountains of onions and garlic before kissing scenes with Hutcherson, just to punish him. Ouch.

6. Suki Waterhouse

Suki Waterhouse needs to go into the dog house after admitting to this particular habit. She admitted to a magazine back in 2014 that she hates having to get dressed for bed, so instead, she has come up with an ingenious solution to this little dilemma.

She told the website Into the Gloss, “I just hate getting changed for bed. It’s a bad habit, but I will sleep in all my clothes, under the covers.” That’s gross! The best thing about getting into bed is snuggling in your pyjamas underneath the warm duvet! Hopefully, she at least changes the sheets…

5. Kate Upton

Kate Upton is one of the stars of Sports Illustrated magazine, so she makes a fair amount of money off her looks. But back in 2015, Upton shattered the illusion that models everywhere possess the highest standards of personal hygiene, admitting to having a severe nail-biting problem.

Upton was discussing nail polish when she made the shocking confession: “I bite my nails so a simple nude makes them look longer!” Apparently, the model regularly chomps down on her nails and they’re so short that she has to compensate with her nail polish.

4. Avril Lavigne

Lavigne’s spitting habit hit the headlines in 2007. The singer was caught snogging her husband Deryck Whibley of the band Sum 41 in the back of the car by some paparazzi and decided to get her own back by spitting directly into the camera lens. Eww!

“I don’t know what the big deal was,” she told Jane magazine later that year. “I’ve been spitting at paparazzi the past two years I’ve lived in L.A. These are annoying guys who follow me around every night and wait around for me. It gets stupid. What if they do something? It should be illegal.” Fair enough Lavinge!

3. Courteney Cox

Courteney Cox rose to prominence after playing the obsessive clean-freak Monica on the hit sitcom Friends, so it’s kind of ironic that her character’s habits never really managed to rub off on her. Cox’s ex-husband David Arquette once ratted her bad habit out to the media.

Apparently, Cox has a very distinctive odour – she “smells like a truck driver” according to her ex-husband. It turns out though that Arquette was a big fan of her personal odour though. The full quotation reads as follows: “Courtney may be pretty, but if she’s not on top of it, she smells like a truck driver and I like it.”

2. Zac Efron

Zac Efron is an actor famous for looking after himself, eating healthy, hitting the gym and even travelling the world to learn about eating and living well. Unfortunately, the High School Musical alum is actually a member of the Brad Pitt club aka he only uses baby wipes to keep clean.

Efron hates having a shower after intense workouts, which is already one of the weirdest things we’ve ever heard. So instead of having a wash, he makes sure to pack some baby wipes instead. How on earth is that going to clean all of his sweat after exercise?!

1. Snooki

And finally, Snooki from Jersey Shore really needs to rethink her facial routine. After the curtain finally came down on the MTV reality show, Snooki wrote a book about her life on the programme, with one particular section from the memoir really catching the attention of fans…

Allegedly, Snooki uses cat litter as part of her facials, specifically to exfoliate her pores. How on earth did she get into that routine? She claimed, “If you want a good facial and stuff like that, it actually really works.” She did add, “It has to be clean kitty litter. It can’t be… poo.”
