That 70's Show and Forgetting Sarah Marshall's sexy leading lady Mila Kunis told BlackBook about her new role in The Black Swan and her lip lock with co-star Natalie Portman. Black Swan director Darren Aronofsky hit box office gold while resurrecting Mickey Rourke for the role in The Wrestler and it looks like he will use that same magic for the young starlet, "I first saw Mila in Forgetting Sarah Marshall," Aronofsky says of his casting pick. "She electrified me and made the screen sizzle. I instantly knew I wanted to work with her."

Kunis plays Lilly, the aggressively disturbed and possibly loony tune whose uptight arch nemesis Nina, is played by Natalie Portman. "It's like a real-life version of the third act of Swan Lake," she says, without revealing plot secrets, "I just feel like such a douche because I can't talk about it. It's not even that big of a deal. It's a fucking movie. It's not like I'm saving the world.

Referring to a rumored sex scene with Portman, "Sure," she says. "It's two girls making out, and guys have a thing for that. And Nat is like every guy's dream. She's a nerd's idea of heaven. The whole thing is silly, but I can see why people care."

The 26-year-old actress also endured a punishing ballerina boot camp for more than two months, practicing seven days a week, five hours each day.

Kunis, who has been discretely dating Home Alone's Macaulay Culkin-yes, that was his last memorable movie-for a few years, also says she wants kids at some point.

Are you looking forward to seeing Kunis and Portman's sexual escapade?
