With Joel heading off on tour and a babysitter secured for the evening, Nicole looked gorgeous stepping out last night for a screening of Trembled Blossoms presented by Prada in Beverly Hills. She was joined by the newest Gossip Girl on the block, Michelle Trachtenberg, as well as the impeccably dressed Taye Diggs and Rosario Dawson. Budding fashion designer herself, Nicky Hilton was out to enjoy the show with her boyfriend David Katzenberg.
