Also slinking down the carpet to the pop and fizz of the paparazzi were Hilary Swank in a black strapless dress, complete with train, and Jessica Alba in an equally figure-hugging, gold-lace-and-chiffon halterneck - both by Donatella Versace, of course - followed close behind by Jada Pinkett Smith in peacock-blue Roberto Cavalli with an artfully draped and pleated bodice, Michelle Williams in a peachy tulle-andsilk crêpe number, also by Vera Wang, and Memoirs of a Geisha star Ziyi Zhang in a black bustier and crystal-studded full skirt by Giorgio Armani.
