Sienna Miller headed out to shop at Ron Herman in LA with a friend yesterday despite the spreading rumors about her alleged affair with Balthazar Getty. While Balthazar himself got the hell out of California, Sienna seems to be business as usual. Sienna looked understandably upset as she entered the shop, though perhaps her love troubles aren't something that a little retail therapy can't fix — on her way out, she was laughing and smiling. It's hard to know yet what the truth is about her and Balthazar, but our sympathy really only lies with his wife and their four kids at this point.
