The stars came out to celebrate the 7th Annual Tribeca Film Festival in New York Tuesday night at the Vanity Fair kickoff party -- and ET was there!

Festival co-founder ROBERT DE NIRO hosted the soiree with native New Yorkers JERRY SEINFELD, BILLY CRYSTAL, EDIE FALCO, AMY POEHLER and more.

With a mission to "enable the international film community and the general public to experience the power of film by redefining the film festival experience," the Tribeca Film Festival was created to help revitalize Lower Manhattan as a major cultural community and filmmaking center and to contribute to its recovery after the tragic events of 9/11.

In addition to films in competition, the festival features gala premieres of the WACHOWSKI BROTHERS' 'Speed Racer' and TINA FEY's 'Baby Mama,' as well as a special 40th anniversary, restored-cut screening of SERGIO LEONE's 'Once Upon a Time in the West.'
