'Twilight' star denies Grenier romance

Twilight star Ashley Greene has laughed off speculation that she is romancing Entourage's Adrian Grenier.

The actress, who plays Alice Cullen in the vampire saga, was rumoured to be dating Grenier after they were allegedly spotted together in Los Angeles twice last week.

Speaking to Access Hollywood, she said: "They are rumours. We met at a surfing event and I haven't seen him since."

Grenier later confirmed her denial, saying: "You said it yourself, rumours. Come on, [you] can't get snapped with anybody without them saying something!"

Greene can next be seen in The Twilight Saga: New Moon, which hits cinemas in November.
