(entertainmentwise.com) - Sienna Miller and Balthazar Getty were reunited after three weeks apart in London last night. The two were unusually reserved in front of the cameras as they exited private member's club, The Groucho. Sienna has been under scrutiny in recent months for dating the married father of four, but the couple seem determined on battling the backlash. The Edge of Love star looked her usual stylish and relaxed self in denim hot pants, military jacket and white pumps. In a recent interview she was quick to point out her anti-diva ways. She said, "When I'm not working, I want to be myself. "I don't have assistants, bodyguards or even a driver because I try to pretend in my own head that this isn't happening. She told Sky magazine: "I think a lot of actresses live in this cotton wool world but I'm very free-spirited and I want to be able to live the life I do." Despite three weeks apart the couple have been glued to one another, sparking rumours that they are house-hunting in Los Angeles.
