The biggest surprise of the night was New York's own Lady Gaga, standing without a handler, in head-to-toe Versace. She was escorted by her bestie, Sir Elton John, who held his AIDS Foundation's annual viewing dinner earlier in the night. The highlight of my night was when Bruce Weber introduced me to living legend Mickey Rooney, and here's what else I spied inside the Vanity Fair party: Illustrious Londoners Tom Ford and Richard Buckley chatting children Georgina Chapman, in a sea of feathers, holding Oscar court with husband Harvey Weinstein Fashion world faves Thom Browne and Andrew Bolton, hands-down the chicest men Jennifer Lawrence, who had changed out of her red Dior gown and into a Tom Ford mirrored mini-dress New York's finest -- Andy Cohen, Kelly Ripa and Mark Conseulos -- amusing themselves by taking selfies The likes of Andrew Saffir and Brett Ratner effortlessly navigating the celeb waters Follow Kelly on Twitter @KellyBensimon or visit KellyKillorenBensimon.com.
