Mila Kunis Recalls 'Awful' Diet for 'Black Swan': Cigarettes and 1,200 Calories a Day

Mila Kunis admits to smoking a lot while losing weight for "Black Swan."

Mila Kunis is getting honest about how she achieved her dramatic weight loss for her role as a ballerina in Black Swan.

The 32-year-old actress appeared on Howard Stern's SiriusXM show on Tuesday, when she talked about how she got the part of Lily in the critically acclaimed 2010 film. Kunis says she Skyped with director Darren Aronofsky prior to nabbing the role, who sought her out after seeing her in the comedy, Forgetting Sarah Marshall. Kunis had never had any previous experience in ballet, but trained for three months in order to "fake it." Kunis acknowledges that she got "crazy thin," as Stern puts it, weighing about 95 pounds.

"I didn't starve myself," Kunis, who's 5' 4," stresses. "I did do it in the healthiest way possible. I don't recommend anybody ever doing it."

The Bad Moms star says she smoked cigarettes and went on a 1,200 calories a day diet to lose the weight.

"I never watched what I ate [before]. It was one of those things, for the first time in my life, I got a food delivery service," she recalls. "And I'll tell you this -- I'm not promoting this at all -- but I used to be a smoker, and so I smoked a lot of cigarettes and I ate a limited amount of calories."

"Twelve-hundred calories and I smoked," she reiterates about her weight-loss methods. "I don't advocate this at all. It was awful."

Kunis says she has since quit smoking, and calls it the "best decision" she's ever made in her life.

Though her struggle eventually paid off. Kunis was nominated for her work in the dark drama for Best Supporting Actress at the 2011 Golden Globes, but she says she felt no pressure during awards season. The actress recalls sneaking alcohol during the Oscars and happily taking shots.

"I think I, at the Oscars, had the best time of anybody, because I snuck liquor in, I did shots," she laughs. "I knew I was not going to win. It just didn't even cross my mind, it doesn't even matter. Like, I literally had the best time. I was like, 'This is crazy, you guys, is anyone else aware of how crazy this is?!'"

"At this point I had a routine on my way to the awards show, like, 'Shot of vodka in the car, woo hoo!'"

Kunis says getting acting accolades has never been important to her.

"I love what I do but I don't need to win," she explains. "Like, I just need to work."
