Robert De Niro, Whoopi Goldberg, and Sienna Miller were among the stars who stepped out for Vanity Fair's Tribeca Film Festival kick-off gala last night (April 16).

The annual celebration marks the beginning of the New York-based festival De Niro and friends started 10 years ago. Actors, models and designers -- including Vera Wang and Carolina Herrera -- were among the party's attendees, as was New York City Police Commissioner Ray Kelly.
