Mila Kunis Modeling for W Magazine: Mila Kunis has vowed to never dance again after the grueling training she went through for her latest film, Black Swan. The Ukrainian-born beauty admits that before taking the role of a ballerina in director Darren Aronofsky's psychological thriller she had never danced before.

"I had never danced in my life. I trained for four months, seven days a week, five hours a day," she says; adding, "I had one day off on my birthday. I lost 20 pounds. I tore a ligament. I dislocated my shoulder. I have two scars on my back.

But don't expect her to take on another role that involves dancing anytime soon. Despite explaining that her experience was "worth every minute," she's not too keen on going through it again.

"[I] will never dance again... I was like, Well— I wear heels; I can do this. I was wrong: Christian Louboutins are uncomfortable, but I screamed the first time I put on a pointe shoe," she says.

Kunis, who got her big break starring as Ashton Kutcher's girlfriend on That 70s Show, also talks about how acting interfered with her college plans and how choosing her roles carefully became a big part of her career. And despite one of her first roles in the business being inexplicable to her she says, "I couldn’t imagine doing anything else."

And that early role? "I was on Baywatch twice. The second time, I played a blind girl who's lost in the forest next to the beach and needs to be saved. It was absurd: There's a fire, I get saved, and then I go boogie-boarding. I remember thinking, Well, if I'm blind, how am I boogie-boarding? No one ever gave me an answer."
