urx unit loader Chris Brown dances to Michael Jackson's 'Thriller' at Diddy's White Party

P. Diddy's infamous White Party, usually held in the Hamptons or in NYC, was held in L.A.  this year, probably because everyone who was anyone was already on the West Coast for Michael Jackson's funeral and memorial Tuesday.

Check out this insider video that captured Brown doing his finest "Thriller" moves. He was later seen making major moves on Rhianna's outspoken pal Kayne West's ex-girlfriend Amber Rose.

The flirty pair were even reportedly lip-locking on the dance floor. This even though he brought his rumored girlfriend, Teyana Taylor, and both sported matching red lightning bolt hair bits on the backs of their heads.

Yikes. Payback is a bee yatch.

The event raised awareness for Malaria No More.

Among the white-clad famous guests, cohosts Demi Moore and Ashton Kutcher, Khloe Kardashian, Russell Brand, Tyrese, Shanna Moakler, Lindsay Lohan, Mariah Carey (in a David Meister gown) and Nick Cannon and Jonah Hill.
