Billed to portray a ballerina in "Black Swan", Mila Kunis seems to have been practicing very hard for the role. According to IMDb, the actress has been left battered with bumps, bruises, cuts, and a separated shoulder because of her clumsy nature. She is now reportedly covered with bandages as she walks limply around the set and wishing she was more careful.

Explaining about her injuries, Kunis stated, "I'm broken. I've pulled so many ligaments, I have tendinitis in my left knee... I had to get an MRI because I popped my shoulder out, and then it inflamed. My toes and hips are bruised." However, her three-month preparation for the film has given her a reward of great shape. "I'm in the sickest shape I've been in my life by far. I'm also on a really strict diet. I'm dieting, then working out three or four hours a day," the 26-year-old beauty said.

In "Black Swan", Mila Kunis plays a ballerina named Lilly, who competes with veteran ballerina Natalie Portman's Nina when both of them are preparing for a big performance. Additionally, Vincent Cassel, Winona Ryder, and Sebastian Stan have also landed roles in the film. Directed by Darren Aronofsky, the movie is currently in production in New York City and is planned to be dropped in U.S. theaters sometime in 2010.
