Yves Saint Laurent sponsored the 125th Anniversary of the Metropolitan Opera House Sunday night at Lincoln Center which included a gala performance of fully staged scenes from classic Met productions. The guest list was jam-packed with stars who attended the YSL affair dressed to the nines including Mary-Kate Olsen, Claudia Schiffer, Claire Danes, Brooke Shields, Parker Posey, Jeremy Irons, William Dafoe, Becki Newton, and Kanye West who seemingly has not left his new girlfriend Amber Rose's side once since they were first spotted together in January.
