John Mayer took some time away from best boy Ricky Van Veen (top photo) to mingle with Carey Mulligan, leading her through the venue hand-in-hand and introducing her to his friends, while Adrian Grenier had his eye on Katie Lee Joel, but didn't seem to know who she was. ("What's your full name?" he asked, tapping her number into his cell phone).
The gorgeous Zoe Kazan held nothing back - dancing feverishly in a baby blue number - not even quitting when missed her step and fell over on the floor, while Ed Westwick channeled a Sex Pistol, showing up in a trimmed biker hat and leather jacket.
Only in New York, kids.
