Seriously, the guest list for Christian Audigier's party was so far off the chain, we haven't even gotten around to showing you half the celebs who showed up yet! Check out our gallery of the festivities to see some pix of Pamela Anderson, Snoop, Mena Suvari - and, of course, plenty more pix of Britney and Michael and others, too!

And seriously, wait until you see the video we've got coming from the party - peeps were getting wild!
