Even though Hollywood's A-List was deprived of a chance to eat and drink on Vanity Fair's dime last night, two fiestas proved that celebrities will not let a little thing like tradition get in the way of a night of free booze and swag. Elton John's Annual AIDS Foundation Oscar Party usually has a strong turnout of power players, but the star wattage at the 16th incarnation of the bash last night was a few standard deviations past the norm, thanks mainly to the absence of Graydon Carter's soiree. Highlights included Tilda Swinton kissing her Oscar in some sort of Buddhist mating ritual, as well as the public debut of Hollywood's newest power couple, Sean Penn and Petra Nemcova. We've got pictures after the jump.
