co-stars Lisa Edelstein
and Olivia Wilde
both chose dramatic floor-length gowns with plunging necklines (Edelstein's was Georges Chakra and Wilde wore Gucci
). "I love this event because we all get to sit together and have some champagne and share a laugh," said Wilde of being able to hang out with her colleagues off the set. "It's just smaller and more fun than all the others."
