Robert Pattinson: Who Is He Kissing in France?

Robert Pattinson gives good lip service.

Kisses from the man himself were just auctioned off for oodles of money at the Cannes Film Festival.

Read on for all the kiss-and-tell details...

R.Patzz was a guest at tonight's ber-chic amfAR benefit, sitting at a table with Italian designers Domenico Dolce and Stefano Gabbana (yes, Rob was in a D&G tux) and French Vogue Editor-in-Chief Carine Roitfeld.

Movie mogul Harvey Weinstein joked from the stage that his daughters changed their last name to Pattison after they saw Twilight. "Harvey then suggested auctioning off an opportunity for someone's daughter to meet and get a kiss on the cheek from Pattinson," a fellow partygoer says. "There were two bidders who paid 20,000 euros each for their daughters to have that kiss."

In U.S. cash, that's about $55,000!

"Harvey put him on the spot, in a playful way," my source says. "And Rob agreed to it in his usual brooding, modest way."

P.S.: The winning bidders were not the parents of Kristen Stewart or Nikki Reed.

Also at the annual AIDS benefit were former prez Bill Clinton, Sharon Stone, Josh Hartnett, Elizabeth Hurley and professional partyers Paris Hilton and Doug Reinhardt.
