"You literally can't spit in here without hitting someone famous." So said one familiar face at the Armani-hosted party at Bungalow 8 after the Met ball last night, which also served as a birthday party for George Clooney (Amy Sacco raced out of the Met early to prepare for the festivities, causing a few tongues to wag). And the observation wasn't an overstatement—walking through the middle of the legendary late-night establishment (which was no easy feat, by the way) was like walking through the pages of a glossy magazine. Eva Mendes, Amber Valletta, and Francisco Costa chatted with Kelly Klein and Aerin Lauder Zinterhofer at the first circle booth on the left; CBS's Leslie Moonves held court at the polka-dot booth on the right; next to him was Valentino Garavani's table; three tables in on the left had Tom Cruise and Katie Holmes, Harvey Weinstein, David and Victoria Beckham, Domenico Dolce and Stefano Gabbana, and Dita Von Teese, the last propped up on a palm tree; across from that table was Allegra Versace, Hilary Duff, Brendan Shanahan, and Sean Avery, in a tuxedo jacket with beaded lapels; at the bar were Chace Crawford, Cat Deeley and Christopher Bailey, and Scarlett Johansson; and in the upstairs lounge, Mary-Kate Olsen, Jacquetta Wheeler, and Byrdie Bell found space and a view. "This is the most glamorous crowded disaster ever," one Oscar nominee sighed. But many would agree that the close quarters were worth it, especially when, a little after midnight, John Mayer led the room in a round of "Happy Birthday" and then crooned out a couple of Sinatra-esque hits with Fergie. From her seat in the last circular booth on the left, Ellen Barkin put it best. Nudging Sacco, she said, "Just another night at Bungalow, eh?"
