Even Hollywood’s biggest juggernauts aren’t immune to some seriously nasty habits. Some celebrities like their stinky snacks way too much, while others shouldn’t be allowed to shake hands with anyone ever without wearing gloves. These on-set stories prove that even famous people still need to learn some manners.
Now, the time has come to spill the beans on these stomach-churning antics.
1. Jennifer Lawrence’s Stinky Snacks
Jennifer Lawrence’s pranks on set are legendary, but her food choices left Liam Hemsworth dreading any sort of intimate scenes in The Hunger Games. Hemsworth confessed that Lawrence often ate garlic, tuna, or Doritos right before kissing scenes and would gleefully announce she hadn’t brushed her teeth. Apparently, she thought it was hilarious! Fans loved her candid attitude, but Hemsworth’s reactions became a meme-worthy moment.
2. Dwayne Johnson’s “Pee Bottles”
When it comes to workout routines, none are as effective and iconic as The Rock’s, but so are his unconventional bathroom habits. Johnson admitted to peeing in water bottles at the gym, and he sometimes did the same on set. While it may not be his proudest achievement, The Rock claimed it saved time during long shoots. According to an insider, he didn’t even throw away the “used” bottles but instead left them for his assistants to clean up. That’s even more gross than starring in The Scorpion King.
3. Frank Sinatra’s Gum Storage
On the Can-Can set, Frank Sinatra showcased his old-school charm and some sticky hygiene habits. When Shirley MacLaine complained about needing gum during a scene, Sinatra casually peeled a piece from behind his ear and handed it to her. MacLaine later joked that Sinatra thought it was perfectly normal. And that wasn’t his only gross habit—Sinatra and his buddy Dean Martin reportedly lobbed spitballs at unsuspecting cast members during tense moments in The Children’s Hour, frustrating everyone involved.
4. Will Smith’s Foul Farts
Even Hollywood’s most charismatic star, Will Smith, has embarrassing moments. While shooting Men in Black, Smith let loose a fart so intense it derailed an entire scene. Director Barry Sonnenfeld recalled the incident vividly, explaining how Smith and Tommy Lee Jones were stuck in a confined car rig when the stinky bomb dropped. Jones tried to remain stoic but couldn’t escape fast enough once the rig opened. The smell was so overpowering that Sonnenfeld claimed that it forced an unexpected break for the cast and crew. Smith later laughed about it on Red Table Talk, admitting he’s “kind of a serial farter” thanks to his bad habit of holding it in too long.
5. Johnny Galecki’s Gum Wall
The Big Bang Theory star Johnny Galecki left his mark on the set—literally. Over the show’s 12-year run, Galecki made a habit of sticking his chewed gum on a stairwell wall frequently used for filming. Co-star Kunal Nayyar once joked that the gum wall had become a weird goop art piece by the series finale.
6. Shailene Woodley’s “Dirt Supplements”
Shailene Woodley is known for her commitment to a natural lifestyle, but her health choices sometimes clashed with her co-stars’ comfort. While filming The Spectacular Now, Miles Teller revealed he had to endure close contact with Woodley’s Chinese diet supplements. These supplements, meant to detoxify the body, reportedly gave her breath and sweat a metallic, earthy smell. Teller described kissing scenes as particularly unpleasant, joking that he felt like he was making out with a compost bin.
7. Jared Padalecki’s Gum Stash
Jared Padalecki’s gum antics on the Supernatural set were just as gross. Jensen Ackles revealed in an interview that Padalecki would routinely stick chewed gum onto counters in his trailer, only to later pop the same piece back into his mouth. Jared swears it tastes better after airing out, though Jensen admitted it made him gag every time he saw it happen. Padalecki defended his unusual habit, claiming it’s a quirk he’s had since childhood, but fans found it either hilarious or plain disgusting.
8. Bradley Cooper’s Tobacco Habit
During the filming of He’s Just Not That Into You, Scarlett Johansson observed one of Cooper’s most disturbing habits. Cooper, who chewed tobacco at the time, spit into a cup during a conversation with Johansson. According to witnesses, a string of saliva trailed from his mouth to the cup, leaving Johansson visibly horrified. That poor woman saw one of the most disgusting things in her life, but she pushed through. Cooper later admitted he felt embarrassed about the incident and quit chewing tobacco shortly afterward.
