Natalie Portman and Mila Kunis: 'Black Swan's' Big Lesbian Sex Scene

Now that The Wrestler has reestablished director Darren Aronofsky as one of Hollywood's hottest and most visionary talents, Universal Pictures has put his once-languishing project Black Swan on the fast track. Signed on to star in the new film are Hollywood A-lister Natalie Portman (far right) and rising starlet Mila Kunis (far left), who will reportedly have some steamy and explicit sex scenes in the flick if the current script is fully realized.

The blog ScriptShadow reports that the Black Swan script calls for Portman and Kunis to have not just sex but "ecstasy-induced hungry aggressive angry sex."

Written by Mark Heyman and Aronofsky, based on an original script by John McLaughlin, Black Swan is about a top New York City ballet company and the fierce competition among a gaggle of ballerinas for the lead role in a new production of Swan Lake.

In addition to The Wrestler, Aronofsky's films include Pi, The Fountain, and the critically acclaimed Requiem for a Dream, which earned Ellen Burstyn an Oscar nomination. Black Swan is due in 2010.
