1 Avril Lavigne
This addiction should come as no surprise. Avril Lavigne admits to being obsessed with black eyeliner. The singer has not been seen without raccoon eyes since hitting the music scene. When speaking on her addiction, she says, "The thing that I'm most addicted to is black eyeliner. It's been my obsession for years."
2 Scarlett Johansson
It's hard to believe after watching her kick ass as Black Widow in The Avengers, but ScarJo is a buffalo wings addict. "Oh my god [I am obsessed] with buffalo chicken wings... You will have to roll me down the red carpet next time you see me," the actress told FOX411's Pop Tarts column. "I can't stop eating them, I just can't get enough." Now that's she's off of her strict Avengers diet, Johansson can finally eat all the buffalo wings she wants.
3 Salma Hayek
Salma Hayek is addicted to breastfeeding! The actress, who gave birth to daughter Valentina in 2007, says she can’t stop. She said: “I’m like an alcoholic. It is like, I don’t care if I cry, I don’t care if I am fat, I am just going to do it for one more week, one more month, and then when I see how much good it is doing her and I can’t stop.”
The 42-year-old also said breastfeeding does not helps mothers shed post-pregnancy weight. She told Style magazine .“The myth that says you lose all this weight when you breastfeed! That is so not true! It’s like, please, will everyone stop telling me I look really well.”
4 Taylor Momsen
Taylor Momsen is a very beautiful and talented actress. To top that, she is also a musician and an actress but guess what? She is addicted to Horror. According to her, during her free period all she simply wants to do is to sit in one corner and start sewing her dolls which are in fact always crappy and very ragged.
Her obsession with these things got so much so that a while back, her neighbours had to call the police on her. The charges includes the fact that she hangs this deformed looking dolls on the outskirts of her house. It got so bad that it became a reference point but then she said it’s her hobby and she won’t give up on them even if they keep calling the police on her.
5 Nicole Kidman
The actress, who is currently filming ‘Australia’, revealed treating herself to cakes and pies is her one of guilty pleasures. The stunning star also insists she will never cut out her favorite foods or obsess about her body.
She revealed, “I can’t have a piece of cake every single night – but I can have a piece of cake three or four nights a week! I eat healthily, but I also love pies and chocolate. I’ve always had this long, lean body type and I haven’t changed since I was 15. I have a boy’s body. I would love to have boobs and a butt like Jennifer Lopez, but I’m not having surgery so there it is."
6 Megan Fox
American actress Megan Fox has revealed that she has an obsession for designer shoes. The 22-year-old actress admits that she doesn’t spend money in silly ways but when it comes to buying glamorous shoes the ‘Transformers’ star doesn’t hesitate to splash out huge amounts.
"I still don't really spend my money in silly ways. I don't go and buy cars and stuff like that. But the very first thing I got that was crazy expensive and that I couldn't believe I'd bought was a pair of Roberto Cavalli, four-inch spike heels,” Contactmusic quoted her as saying. "That was a really big deal for me and I have to admit that since then I've gone crazy with the shoe thing. That's where I spend my money and it's really bad," she added.
7 Katy Perry
Katy Perry has a very high obsession of always brushing a lot of times daily. Most times, Katy brushes almost 12 times a day. Hers is so much excessive that her dentists actually warned her that if she doesn’t stop, her enamel will begin to pull out one after the other. But then she keeps about 20 brushes handy every time. She says she is so terrified of having bad teeth hence the excessive tooth brushing.
8 Anna Kendrick
Twilight star 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. She admitted to PopStop TV, "I have like 4 stars on every level. It's disgusting how much I play that game. It's not like, 'Oh, what level am I on,' It's like, 'Do I need therapy to break myself from playing Angry Birds?'"
She has also admitted to being addicted to Reddit and Snapchat, both of which she uses throughout the day. Between the video games, online forums, and text messaging applications, it would be safe to say that Anna Kendrick is addicted to technology, particularly to mobile. There’s good news for Anna though.
9 Emma Watson
Emma Watson may be leaving Hermione Granger behind on the film set, but not in her heart - the actress says the two share a similar passion for learning. Watson, whose character in the Harry Potter movies made it cool to be a studious teacher's pet, says she's "addicted to knowledge" and motivated to keep learning while doing other film projects.
In an interview, the actress shared that she was addicted to learning. She says, "I just love learning. I'm, like, addicted to learning. I just want to know as much as I possibly can." This is one of the reasons why she is truly a girl with beauty and brain unlike most Hollywood celebrities
10 Jessica Simpson
Jessica Simpson made headlines when she revealed that she became addicted to nicotine chewing gum — even though she had never smoked. Simpson said that a piece of the gum proved more effective at energizing her than three Red Bulls. “The first time I ever chewed a piece of Nicorette gum, one of my close friends’ mother gave it to me. I was chewing it and it was like a party in my mouth. It was like fireworks and ‘Oh my god, I’m talking a million miles per hour and I love this gum and what kind of gum is this? I have to have this gum,'” Simpson recalls.
11 Robert Pattinson
Robert Pattinson's two weird addictions might end up getting him into some trouble. Turns out the vampire has a sweet tooth. Robert Pattinson, best known for his role in the Twilight series, allegedly once drank 300 cans of Diet Coke in one week—that's 43 cans a day! (Okay, so maybe it's a myth). In addition to his Diet Coke addiction, Pattinson also loves Cinnamon Toast Crunch cereal and eats it constantly. Sure, that's a lot of sugar, but at least he's addicted to soda and cereal rather than blood.
12 Cheryl Cole
Cheryl Cole's eyesight must be off the charts amazing, because she consumes multiple glasses of carrot juice a day. It's no wonder she has such beautiful hair, nails and skin. Carrots are full of Vitamin A, which is great for your skin and prevents dryness. Her friends claim she became addicted to the vegetable while on holiday in South Africa. "Cheryl told everyone she was addicted to carrot juice as it makes her skin glow and helps her nails stay long and strong. She’d start the day with two glasses then order up to six glasses by the pool with a tray of smoked salmon," said a source.
It does seem that if she doesn’t curb her addiction to carrot juice, she will be forever known as the orange-tinted singer from England. Now when we see Ms. Cole on X-Factor, we’ll wonder if that cup they all drink from contains water, soft drink, alcohol, or carrot juice.
13 Jesse Eisenberg
Jesse is well-known for his roles as a lovable geek and for playing Mark Zuckerberg in the movie “The Social Network.” In the future, however, Jesse might become better known for his peculiar addiction to adopting stray and foster cats. In a 2011 interview he admitted to having 42 cats. The more movies he does, the guiltier he feels about not helping enough cats.
It’s great that he wants to provide a home for furry felines, but what is the difference between a good deed and becoming that crazy type of cat person? Maybe the addiction is fitting, however, now that Jesse Eisenberg has been cast in the role of Lex Luthor in Zack Synder’s upcoming film “Batman vs. Superman.” Isn’t it the case that villains have cats? So would it not logically follow that the more cats the villain has, the more evil he or she is? Perhaps this is all some elaborate form of method acting.
14 Shay Mitchell
15 Charlize Theron
You’d think that most Hollywood types would steer clear of anything that’s not vegan, gluten-free, or packed full of superfoods. That seems like a reasonable assumption, especially if you’ve spent any time in Los Angeles. But you probably haven’t met Charlize Theron, who, Glamour learned, has an addiction to fried food. Theron told the publication of her obsession, “Anything fried, I’ll take. Are you kidding me? I will fry my shoe and eat it.” (At least she doesn’t seem too attached to her shoe collection!)
