Clooney and his Ocean's Thirteen co-stars Matt Damon, Don Cheadle, Andy Garcia and Ellen Barkin made a brief appearance at the annual Cinema Against AIDS dinner, which raised a record $7 million for the Foundation for AIDS Research (amfAR).
As Clooney and his castmates auctioned off a seven-day Mediterranean getaway on a private boat, Stone announced: "If you bid, one of these guys will come down and touch you. And you can choose which one."
But the choice was clear. With flourish – and on stage – Clooney promptly kissed the lucky girlfriend of the winning bidder, who'd ponied up $350,000.
"I'll kiss [Clooney] for $500,000," joked Ellen Barkin. And as dozens of guests clicked their camera phones, Clooney then kissed her, too.
There was more talk of kissing later in the evening, when Lost's Michelle Rodriguez teasingly offered to smooch Stone if bidders would go higher on a private tennis lesson from guest Monica Seles. (The bidders did, but Rodriguez didn't pucker up.)
The night also featured an impromptu performance from Kylie Minogue after guests – including Naomi Campbell, Claudia Schiffer, Eva Mendes, Goldie Hawn and Kurt Russell – joined together to bid $300,000 for two songs. Minogue, who'd been sipping champagne and sitting unnoticed at a table with designer Sergio Rossi until Harvey Weinstein summoned her, performed "The Locomotion" and "Can't Get You Out of My Head." Stone jumped onstage to join her.
Other entertainment for the night: Dita von Teese's burlesque act, built around a 9-foot MAC Viva Glam lipstick. And as guests finished their dessert of peach melba with chocolate, John Lennon's son Julian closed the night with "Stand By Me." "I've never been involved in anything like this," Lennon said. "It's an overwhelming experience."
Other guests at the dinner included Mischa Barton, Rosario Dawson, Rose McGowan (who held hands and snuggled much of the night with Grind House director Robert Rodriguez), Kerry Washington and Bond girl Michelle Yeoh. "I think it's great in the middle of such dolce vita to raise money for something so important," McGowan told PEOPLE.
