amfAR's 2008 Cinema Against AIDS Gala

For the 13th year in a row, Sharon Stone called upon her famous friends to help raise money for the fight against AIDS at the annual amfAR Cinema Against AIDS gala in Cannes. Madonna (in Stella McCartney) and Sean Combs each auctioned off one-on-one time-Madge sold a private performance for two, and Diddy offered his highest bidder the chance to roll with him for 24 hours-while singer Mary J. Blige (in Marchesa) inspired the crowd with a three-song set. Madonna also put her own Chanel bag on the block, but drew the line when Stone offered one bidder the chance to make out with the Material Girl. "I'm worth more than a million dollars," said the singer, who kept her lips to herself. Still, despite the absence of celebrity PDA, amfAR raised a record-breaking $10 million dollars. "I just feel privleged that I can help," said a humble Stone, taking her seat for the first time as her guests made their way home.

Natalie Portman took a break from her job as a festival juror to help auction off a number nine-themed package, which included dinner, theatre and premiere tickets and a private screening for an entourage of nine. The petite actress-who was accompanied by singer Devendra Banhart-stole the style spotlight in a cut-out gown by design house Givenchy.

Mary J. Blige thanked event hosts Madonna, Sharon Stone and Weinstein Company chief Harvey Weinstein before kicking off a three-song set that included a cover of U2's classic, "One." "Do you want to be lifted up?" Blige asked the crowd before launching into "Family Affair," which eventually got Diddy onto his feet.

During a dinner of classic French cuisine prepared by renowned chef Alain Llorca, Joshua Jackson captured the moment with his Flip video camcorder. Looking luminescent in a vintage Chanel Haute Couture dress and diamond pendant by Chanel Fine Jewelry, Diane Kruger was the perfect subject for her amateur auteur boyfriend.

Sharon Stone worked her magic as she tried to sell P. Diddy a private portrait sitting with famed artist Julien Schnabel. "I like your dress," said Diddy, trying to distract Stone, who would not be deterred. When the actress (in Roberto Cavalli) tried to squeeze the rap star for more than half a million dollars for the item, Diddy-who is staying aboard his private yacht while in Cannes-claimed his pockets were empty. "I don't have 320,000 Euros," he said.

Burlesque performer Dita von Teese (in Gaultier), who provided the steamy show at last year's gala, gave a preview of the item she auctioned off-a personal strip tease at the winner's home. As Milla Jovovich warbled in the background, Stone asked the crowd, "Anybody out there got $50K for a good time?"

After showing the gala crowd a clip from her heartbreaking documentary, I Am Because We Are, Madonna got into the spirit of giving-and taking. "I'm going to make this more intriguing for you, I'm going to put stuff in it that's mine." Madge told the audience as she showed them a one-of-a-kind Chanel alligator bag personally designed by Karl Lagerfeld. After transferring Shu Uemura blotting papers, a lip gloss and magnifying mirror over from her own purse, Madonna kicked off the bidding. "I've basically dumped out the entire contents of my handbag and put it in this bag," she said.

Marchesa designer Georgina Chapman dressed model Petra Nemcova in a white goddess gown for the occasion. How does Nemcova-who slipped away from Cannes for a two-day trip to New York City-stay looking gorgeous despite all the late nights? "I just believe that if you are happy in your heart, that shines through and makes you beautiful," she said. "That, and I drink lots of water!"

Rose McGowan managed to hide a bulky cast under her chic Dolce & Gabbana gown. "I broke my foot two weeks ago, but there was no way I was going to miss this!" the actress declared. McGowan even managed to pull off a Sergio Rossi stiletto on her good foot. "I put padding under the cast and now it's the same height as the heel," she explained. "I refuse to wear flats [in Cannes]!"

"I told you we we're going to make history tonight!" said designer and amfAR Chairman Kenneth Cole after hitting the $10 million mark. For her part, the unstoppable Sharon Stone started the fundraising early, drumming up $2 million dollars before the auction had even begun. "This year I had my 50th birthday. I didn't have a big party and I gave away half of my belongings," said the activist. "For my birthday amfAR, I decided to start a pediatric branch where we grant money for pediatric AIDS research around the world."
