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!
1. Megan Fox

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.
2. Anna Kendrick

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.
3. Robert Pattinson

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.
4. Cheryl Cole

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.
5. Avril Lavigne

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.
6. Michelle Williams

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.
