New York Magazine seems to have confirmed Page Six's account of Anna Wintour dancing at Monday's Costume Institute Gala. At a Sean Jean press conference this morning, attendee and DJ Diddy stated: "[Anna and I] danced a little bit. Yeah, she danced with me. I made her dance. I made Oprah dance." Possible photographic proof, via BBC, is above. The angle makes it impossible to say for sure, but they also don't call it a "signature" haircut for nothing.
