Cameron Diaz , who was last linked to Criss Angel and John Mayer, got up close and personal with Gerard Butler, the Scottish-born star of 300, at Teddy’s nightclub in LA on March 29. “They ignored everyone else,” an onlooker tells Life & Style. “They just kept getting closer and closer.”

Gerard, 38, couldn’t get enough of Cam. “There was a lot of thigh and arm touching,” says the onlooker, “which got more progressive as the night went on.” Between sips of champagne and water, Cameron seemed to be laughing at all of Gerard’s jokes. “At one point,” the onlooker adds, “she placed her bottle of Voss water between her legs, and Gerard put his hand on it.”

But just as the couple (who also reportedly had dinner together at the Chateau Marmont in LA on March 27) were about to lock lips, a group of tipsy girls interrupted them and asked for a photo. “Gerard was annoyed at first,” says the insider, “but then was amused to discover the girls had no idea who he was. They just wanted him to take a picture of them, which he did!” And then, of course, he got back to canoodling with Cameron.
