Fashion Rocks: 'Slebs Get Sparkly

American starlets. Say what you want about them, but they do give us hours of fun critiquing their outfits when they turn up to a party, an awards ceremony or - in the case of the Rachel Zoe clones - the opening of an envelope. The 'Fashion Rocks' event pulled in a predictable crowd of young 'slebs in everything from leather mini skirts to silver lame evening gowns. See the gallery here and pick your faves. We rate Rachel Bilson's blue one-shoulder sheath and Christina Aguilera's sparkly black number. Not so sure about Fergie, though...
