TWILIGHT’S ROBERT PATTINSON’S HOT HOOKUP

Robert Pattinson really sank his teeth into amfAR’s annual Cinema Against AIDS benefit in Cannes, France, on May 21, auctioning two kisses on the cheek for $28,000 apiece. But the Twilight hunk felt even more charitable at the event’s afterparty at Hôtel du Cap, where he gave one lucky lady lots of smooches — free! Robert, 23, strolled into Eden Roc bar and quickly struck up a flirty conversation with gorgeous LA resident Erika Dutra. “Erika was introduced to Robert by a mutual friend at the beginning of the night,” explains an eyewitness, “and from that point on, he was smitten with her.”

The duo holed up in a cozy corner of the bar’s lush balcony and sipped drinks from 1 a.m. to 3:30 a.m. “Robert took pictures of her, and they were even seen kissing,” continues the onlooker. “There was serious chemistry between them, and they looked like they were having an amazing time.”

As Life & Style has reported, Rob’s been pining for his co-star Kristen Stewart for months, so was Erika just a casual hookup or something more? “It’s absolutely possible that you can meet someone on the street and suddenly fall in love with that person,” Robert has admitted in the past. “That often happens to me.”

He’s aware of how his fame has changed the dating game, though. And Erika, who’s an ex–University of Southern California student and the rumored pal of actor Emile Hirsch, seems to understand Robert’s need for discretion: After befriending him on Facebook and plugging his phone number and e-mail address into her BlackBerry in the early hours of May 22, Erika swiftly made her formerly public Facebook friend list private.
