Celebrities Like Madonna and Sean Diddy Combs auctioned different items in support of AIDS charity, amfAR on the sidelines of the Cannes film festival.

Madonna auctioned a “private concert” late on Thursday at a star-studded dinner, raising 350,000 euros ($560,000).

Sean Diddy Combs auctioned 24 hours in his company, promising: “I will fulfill your wildest dreams for amfAR and the children,” and “I will wake up with you.” The winning bid was 200,000 euros

The biggest lot on a night of conspicuous spending was a restored 1976 Porsche 911, which went for 500,000 euros after rap mogul Sean “Diddy” Combs stopped bidding at 450,000 euros.

The pop star-hosted star-studded bash succeeded in raising more than $10 million for the American Foundation for AIDS Research, a record for the veteran event, which also featured performances from Mary J Blige and Dita Von Teese.

The usual auctioneering was from Sharon Stone , whose Cinema Against AIDS gala is one of the hottest tickets at Cannes every year

Among those spotted walking the red carpet last night were Madonna, Combs, Stone, Natalie Portman, Joshua Jackson and girlfriend Diane Kruger, Dennis Hopper, Juliette Lewis and movie mogul Harvey Weinstein.

While prizes included a private Von Teese striptease (sold for $77,000), a guitar used on Madonna’s Confessions tour ($472,000), and a Stone-owned vintage Porsche ($786,000), some of the more interesting items of the night were those put up on the spot.

Like the contents of Madonna’s purse. Along with her one-of-a-kind diamond-encrusted alligator Chanel bag, Madonna threw in a magnifying mirror, hair clips, skin blotting tissues and the pièce de résistance, lip-gloss.

“This lip gloss touched my lips,” she said by way of prodding higher bids. It fetched $472,000.

The evening was in all a grand success for the charity.
