Diddy moved his annual White Party from the Hamptons of New York to Los Angeles this year, and turned July 4 into a celebration of white, white and more white.

Co-hosted by Ashton Kutcher, who shared highlights of the event with his 2.6+ million Twitter followers, the event featured a roster of celebs including his Mrs, Demi Moore; Chris Brown, Mariah Carey and Nick Cannon, Lil Kim, Lindsay Lohan, Tyrese, Jonah Hill, J.C. Chasez, Tom Green, and even "actress" Marla Maples. (Well, she did famously tell the New York Post that Donald Trump was "the best sex I ever had," so I suppose that counts.)

And for once, Tara Reid (in a slip-proof halterneck) wasn't even the most embarrassing person at the party. Someone invited Tila Tequila.

This year the White Party was to benefit Malaria No More, a charity to protect the developing world from the mosquito-borne disease.

Several videos from the party, including Diddy's speech about the cause, can be found here.

And don't miss this clip of Ashton trying to swing across the pool--although you might want to turn down your speakers, because there's a screamer standing next to the microphone.
