Robert Pattinson Hooks Up With a Hot Blonde After AIDS Benefit!

And no, we’re not talking about Sharon Stone, seen here sharing the stage with Robert Pattinson at amfAR’s Cinema Against AIDS benefit at Cannes on Thursday.

Life & Style reports that Pattinson was making seriously quality time with Los Angeles resident Erika Dutra at an after-party for the black-tie gala.

“Erika was introduced to Robert by a mutual friend at the beginning of the night and he was smitten with her from that point on,” says an eyewitness. “He took pictures of her, sat with her all night, and the two of them were even seen kissing! There was serious chemistry between them, and they looked like they were having an amazing time.”

We’re assuming that Pattinson wasn’t smooching Dutra because she’d won the charity kiss auction that he participated in. Especially since, the eyewitness adds, “Erika and Robert even left the party together!”

Uh-oh; Kristen Stewart isn’t going to be happy to hear about this…
