Jessica Alba donned a skintight dress to the Tribeca Film Festival awards show and bash at the weekend. The birthday girl—Jess turned 29 last Wednesday—kept the drama to her outfit this time, unlike the other night when she set off the hotel fire alarm while making dinner for Honor. Whoops! Fellow TFF juror Peter Facinelli stepped out to help hand out the prizes, while Abbie Cornish and Selma Blair kept the sultry glamour levels high. Channing Tatum was vested up and smiley even without his wife, Jenna Dewan—the Mrs. also got to show off another side of her work this week in Christina Aguilera's sexy new video.
