A Night at the Opera

Emmy Rossum
and Leighton Meester

"I know what happens, so I'm not really missing anything," said Leighton Meester, one of the few twenty-something women in New York City not planted in front of the television to watch an all-new episode of Gossip Girl. But Meester's evening was right out of a GG script; The actress joined Emmy Rossum, Eva Mendes and Naomi Campbell to help fashion house Yves Saint Laurent celebrate its partnership with New York's Metropolitan Opera House at the opening night gala performance of Donizetti's La Fille du Régiment. And while there was no proverbial fat lady, the evening of cuisine and culture wasn't considered officially over until the last glass of Louis Roederer champagne was drunk.
