Emmy Rossum Is Obsessed With String Cheese, and 9 Other Weird Celebrity Addictions

They're just like us! Hooray!

When most people hear the term "addiction," they probably first thing of terrible stories they've heard about drugs or other forms of substance abuse. But there's also such a thing called 'behavioral addiction,' which is when you get so caught up in a habit, like eating a certain kind of food or performing a certain task (maybe spending too much time on the Internet, perhaps?), that you start feeling compelled to do it even when you don't want to.

Ever gotten totally stuck playing a certain app on your phone or grabbing the same order from Starbucks every single day? If so, you're not alone -- even celebrities have to manage the weird habits and hobbies they inadvertently pick up, such as:

  1. Emmy Rossum

    Speaking with The Cut about her workout routine, the "Shameless" star admitted a secret about her eating habits. "I have a string-cheese addiction," she said. "I can't keep them in the house. It's not something I would eat with other people — it's not like I'll pull out some string cheese when I'm having a glass of wine with a group of friends. It's just something I like to have when I'm on the go, and I really don't have to think about it. I guess it could be a lot worse." Hey girl, no shame. String cheese does pair really well with Sauvingnon Blanc.

  2. Kylie Jenner

    On her website, the celeb admitted a serious addiction to changing up her hairstyle, which has damaged her natural hair so much that she's resorted to wearing wigs instead. "I’ve just had this addiction to changing my hair. It makes me feel like a new person. I love feeling different and I love leaving the house knowing that nobody has ever seen me this way,” she wrote in a blog post on her website in September.

  3. Jordin Sparks

    Remember when our girl didn't know how she was to supposed to breath without air? Substitute air for "Pokémon." Yup, the pop star has been obsessed with the classic video game franchise since the beginning and, as she told Twitter last November while she was playing "Omega Ruby," "Every 'Pokémon' game has me addicted until I beat it." Guess she'll be happy to hear that "Red," "Blue" and "Yellow" are coming back, huh?

  4. Jennifer Lawrence

    You probably already know what we're about to tell you about the "Mockingjay" star, because her love of reality television is nigh inescapable, particularly shows like "Real Housewives and "The Hills." "MTV sometimes plays them for, like, three hours, and that will just turn into my morning. Like, I'll cancel s--t,"she told Eddie Redmayne for Interview. Whoops, uh, sorry about that.

    ScarJo's big obsession? "Buffalo chicken wings. I am addicted to them,” Johansson told FOX411's Pop Tarts column back in 2013. “You will have to roll me down the red carpet next time you see me.”

    The "Twilight" heartthrob admitted to The Observer that he has a particularly terrible obsession: reading negative comments about himself on the Internet. “I do read reviews to a fault, and it’s an awful thing to do,” he said. “It’s an addiction. And you only read the bad ones, too, just to foster hatred, self-hatred, self-loathing. Yeah, weird habit.” Aw, no don't do that!

  7. Terrence Howard

    As the "Empire" star told Rolling Stone earlier this fall, he spends a lot of his free time cutting out plastic shapes and connecting them together, which he does as a way of proving his very confusing theories about how we're all doing math wrong. I guess at least they're pretty?

  8. Olivia Munn

    Most people just bite their nails when they get anxious, but not Munn. "I rip out my eyelashes,” she told the New York Daily News. “It doesn’t hurt, but it’s really annoying. Every time I run out of the house, I have to stop and pick up a whole set of fake eyelashes." This behavior is known as Trichotillomania, and it's technically an impulse control disorder. Yikes!

  9. Paris Hilton

    Remember when people used to joke about wanting to do awful things to Paris Hilton, like pushing her out of an airplane? Don't worry, she's already doing that for you. "I went for my birthday last year and got addicted, it’s so much fun. I was [terrified] but it’s such a rush, it’s really thrilling," she reportedly said back in 2007. Of course, we're assuming she's maybe taking a break from the hobby after Egyptian TV presenter Ramez Galal pulled that awful prank on her this summer and made her think she was actually about to die on a plane. That's for sure a buzzkill.

  10. Daniel Radcliffe

    Sure, DanRad is British, but since moving to America he's developed a very strong and probably unhealthy love of American football. "When I got into fantasy football, that’s when my level of obsession with the game increased and my understanding of it grew very quickly as I realized that if I was not going to completely embarrass myself in this league then I was going to have to put in some serious time learning about it," he told The New York Times. His fantasy team name? "Barkevious Mingo’s Mum."
