London: Actor George Clooney's girlfriend Sarah Larson, a former cocktail waitress, has finally spoken out on their relationship, saying he seduced her years back.

The two have been reportedly dating for a year after they first met at the Las Vegas premiere of "Ocean's Thirteen" in 2007.

But Larson claims she first met Clooney at his birthday party years earlier but she was dating some one else at that time, reports contactmusic.com.

She said: "It was on his birthday three or four years ago at Whiskey at Green Valley Ranch (in Las Vegas). He was with his friends and I was with some friends. We were all dancing, taking pictures, being silly."

Larson added that Clooney then looked her up when he got back later. "He heard I was working at Moon (nightclub). We hung out," she said.
