The Prada store in LA was packed on Friday night with starlets celebrating the launch of the label's new book. Jessicas Biel and Alba kept things simple in black, as did mom-to-be Camila Alves. Christina Ricci took a break from her bikini fun with her new boyfriend to get decked out in a bejeweled white number. Chloe Sevigny, meanwhile, sported a bra-bearing look to pose for photos with pal Liz Goldwyn and Big Love costar Ginnifer Goodwin. Rachel Zoe added a little color to the proceedings with her husband Rodger. The Prada party was a prelude to the even more star-studded bash at LA's Museum of Contemporary Art on Saturday, and it looks like the ladies got a head start on their fashionable partying.
