Actress Amber Heard gets to play Penn's special lady in the new thriller "The Stepfather," and she was ready to dish on her on-screen relationship with the "Gossip Girl" star when MTV News caught up with her at the movie's premiere.
"I'm a long term girlfriend," she explained. "I'm member of the family in that way ... He confides in me, and I'm really the only person he can trust. So we have a unique relationship." When everything unravels though, Amber adds, "I'm there for him in a surprising way." We're hoping that means Amber's Kelly goes a little Lara Croft on the titular stepfather's a-- and kicks major butt.
