Everyone has a vice. Maybe it's coffee, maybe it's alcohol, or maybe it's spending too much time watching Netflix.
But these celebrities have addictions that are, well, they're pretty darn weird.
From carrot juice and tanning to eyeliner and online gaming, find out which celebrities have some very strange addictions!
This one is a bit of a cliche, but that doesn't make it any less of an addiction. Megan Fox is apparently obsessed with shoes. Lots, and lots, and lots of expensive shoes.
Anna Kendrick has an obsession we can probably all understand, but she might be more addicted than most. She's totally obsessed with online gaming, and says she plays games for hours almost every day. The game she's most addicted to? Angry Birds.
Robert Pattinson's two weird addictions might end up getting him into some trouble. He's admitted to drinking as many as 300 cans of Diet Coke in a week, and eats way too much Cinnamon Toast Crunch.
Cheryl Cole's obsession isn't so bad, but it's definitely pretty weird. It's carrot juice. She admitted to drinking about 8 glasses a day. EIGHT.
Avril Lavigne's addiction isn't actually very surprising. In fact it's part of her overall look. She's obsessed with, you guessed it, eye makeup.
We've all probably admitted to being addicted to checking email at some point or another, but for Michelle Williams, it feels like "a dopamine hit." She even tried writing letters by hand to help matters.
For Lily Allen, it goes beyond an addiction to checking email. She admitted to being so addicted to the internet, that she had to cut herself off entirely. "I was using the internet in a really destructive way," she said, adding that she'd often look for negative comments about herself online.
Ozzy Osbourne also has an addiction to a sugary cereal, but he has to have his important from England. Apparently, that's the only place that sells Sugar Puffs.
Kristen Bell isn't afraid to admit her obsession. It's with one of the most adorable animals on the planet: sloths. And seriously. Who can blame her?
Selena Gomez is a food combination that seems, well, a little strange. She's completely obsessed with "maple dogs." Yep, that's a corndog topped with maple syrup, kids.
Here's another addiction that is, actually, not bad at all. In fact, it's almost as healthy as Cheryl Cole's carrot juice addiction. Jack Black is addicted to green tea. That's okay, right?
This one could be worse. Sort of. Jessica Simpson once admitted to being addicted to Nicotine gum... even though she never smoked.
Mila Kunis once admitted to Jimmy Kimmel that she was addicted to the game, World of Warcraft, and that she knew she had to quit it.
Here's one that comes as no suprise whatsoever. Paris Hilton is addicted to tanning in all forms. Whether it's fake tanning to getting some sun on the beach, she's got to be tan.
Ed Sheeran? He's completely obsessed with fish sticks. There could be worse things, but this one is definitely pretty weird.
Actress Jane Lynch admitted that she was once addicted to cough syrup, something she was using to replace a bad habit of drinking too much alcohol.
Jersey Shore's Nicole Polizzi, aka Snooki, is known for having an addiction to pickles! She has also admitted to being addicted bronzer, boys, and alcohol.
Simon Cowell is addicted to something called "Angel Delight." It's a powdered dessert from the U.K. that comes in a packet, and you mix it with milk for a pink mousse. Appetizing, right?
We're told from the time we're kids that it's important to brush our teeth, but Katy Perry took that advice a little too seriously. She's admitted to being obsessed with brushing her teeth, and sometimes brushes them six times a day.
It seems like the most common of celebrity addictions is the internet. For Beyonce, that means an addiction to online gaming. One of the reasons she thinks it's fun because she's able to be anonymous.
This one might sound a little cheesy, but Emma Watson is a lot like her most well-known character, Hermoine Granger, in that she's admitted that her addiction is to learning. She was quoted saying, "I just love learning. I'm like, addicted to learning. I just want to know as much as I possibly can."
