But Ashley Greene, who has worked with the star on three of the Twilight films, admits that despite the fame and legions of adoring fans, Robert Pattinson has managed to remain grounded.
She tells Britain's Sunday Times, "As a person, he's not like anyone I've met in Hollywood... He has no ego. Everyone loves him, but he's unaffected by that and never seems fazed by the attention that comes his way. He's not changed a bit since I worked with him on the first Twilight movie."
