Calvin Klein girls of past and present were out to celebrate, with original CK denim model Brooke Shields slipping back into her Calvins, and current perfume face Eva Mendes wowing in a plunging grey gown.

The red carpet included a host of super-stylish stars, such as Claire Danes, radiant in an asymmetric dress, Molly Sims working the strapless look, and Jessica Szohr in an asymetric design.

Gossip Girl Leighton Meester showed off a new look, ditching her preppy florals for a rock-chick worthy high-waisted black leather pencil skirt, while Halle Berry wowed in a slinky fitted gown.
