LOS ANGELES: Amber Heard ‘’calls the shots’’ in her relationship with Johnny Depp. The 27-year-old actress is believed to have just got engaged to her ‘The Rum Diary’ co-star and friends say she’s the woman who has finally tamed him. A source who knows them both said: ‘’Amber has called the shots since day one, dictating when they went public, for example. She’s half his age and that’s part of why he’ll do whatever she wants in order to keep her.’’ Another source added: ‘’He has definitely toned down his behaviour since he started dating Amber. He acts like a mature and charming man now.’’–EX
