Rosario Dawson brought two large pizzas to a catered affair at a private $14 million penthouse for guests to enjoy after a Cinema Society premiere of her latest movie, “Trance.” She also opened up to us Tuesday about the delicate negotiations to go full-frontal in the thriller. “I knew that I would have to deal with it before I even auditioned,” Dawson said at the party. “It was non-negotiable, it was necessary . . . My lawyer and I had this whole moment where we had to talk about [detailed parts of the female anatomy] for the nudity clause and you think, ‘Is this happening?’ It’s kind of wild.” The star was joined at the Montblanc and Grey Goose-sponsored bash by director Danny Boyle (amid news he and Dawson have recently split), Vincent Cassel, Patrick Stewart, Josh Lucas, Emma Watson, John Legend and Chrissy Teigen, Zosia Mamet, Jemima Kirke, Lou Reed, Norman Reedus, Debbie Harry, Paul Haggis, Cindy Sherman and Marina Abramovic.
