Natalie Portman goes sapphic with Mila Kunis in the upcoming "Black Swan." Now she's getting her racy on in a different way.

For the past few weeks, Portman and college friend Laura Moses have been shopping to Hollywood studios a ribald comedy that they have written, said two studio executives who've read the script. http://nataliaportman.blogspot.com/



The project, called "BYO" (for Bring Your Own), concerns two very different twentysomething women who, after finding themselves unlucky in love, decide to throw a party to which each female attendee brings an eligible bachelor. The executives who've read the script describe it as a female-themed "Superbad."

Portman would star as one of the female leads and produce the movie, and the studio executives said they'd been told Anne Hathaway has expressed interest in the second lead role.

The project, which has been passed on by several Hollywood studios, could still get made via either a studio or, more likely, via independent financing. Representatives for Hathaway and Portman could not immediately be reached for comment.

Portman, who has never previously written a movie, graduated from more buttoned-down roles with her pole-dancing turn in 2004's "Closer." "Black Swan" sees her going back to that territory: In the film (which premiered in Los Angeles on Thursday night and opens Dec. 3), she plays a repressed ballerina who lets her hair down in a much-touted scene involving Ecstasy, a rave and sex with Kunis' character.

Now, apparently, she's adding a Judd Apatow notch to her belt, too.
