Seemingly undeterred by accusations of home-wrecking, Sienna Miller was reunited with American actor and oil heir Balthazar Getty in London after three weeks apart.
The two were spotted leaving private member's club, The Groucho.
Miller has been criticised on both sides of the Atlantic for her relationship with the married father and the Edge Of Love actress's mum recently leapt to her defence.
Jo Miller said: "You can't understand how a woman seeing a man who has been separated from his wife for months can cause such a scandal. It's awful, I can't tell you. You wonder when it's all going to stop."
