Who said Anna Wintour was all work, no fun? The devil herself got down last week at the after party for one of New York's biggest fashion events of the year,
the Metropolitan Museum of Art's Costume Institute Gala.
Vogue editor-in-chief Anna Wintour co-hosted the event with Oprah Winfrey. The two invited N*E*R*D to perform and got bang for their buck when P Dids got on the mic too.
Flip through the gallery above for pictures of Anna with her arms in the air like she just don't care, Katy Perry on someone's shoulders in a dress lit up with LED lights, Oprah rocking out in a custom-made navy silk-organza Oscar de la Renta gown and Usher cold chillin' in a pale blue tux.
