Spring gala season is in full bloom and last night brought the Tribeca Ball, at the New York Academy of Art, honoring Peter Brant. The publishing scion and art collector arrived with his full clan in tow -- Stephanie Seymour and the Brant brothers. Other notables included Calvin Klein, Robert De Niro, Brooke Shields, Mary Kate Olsen and Olivier Sarkozy, Parker Posey, Vito Schnabel, Dustin Yellin, and Rachel Feinstein. The flossy array of guests juggled cocktails and champagne, bumping elbows through five floors worth of open studios, before eventually retiring to a seated dinner on the main floor. Check out images of the scene at the ball, below.
