Never mind Prince Harry, leading his team to an 8-4 victory on the polo field. Or actress Cate Blanchett, hoisting her 3-year-old son, Dashiell, on her hip. At the Cartier International Polo event on July 24 in Windsor outside London, stargazers only had eyes for 23-year-old actress Sienna Miller. Just seven days earlier, Miller had been publicly humiliated when her fiancé, actor Jude Law, issued an open apology for cheating on her with his children's nanny.

But at the polo event, Miller – looking exceptionally thin in a black minidress and without her $35,000 engagement ring from Law – put her best high-heeled foot forward.

Smiling for photographers and chatting with other partygoers, including British actor Damian Lewis, she saved an especially warm greeting for Orlando Bloom, with whom she shared a hug and a much-noticed kiss. "I'm okay," she told fellow guests between cigarettes and frequent checks of her cell phone. "It was a long, long week."

It was looking that way for Law too. On the London set of his upcoming drama Breaking and Entering, he has appeared notably glum. "He's going through a tough time," says a source close to the actor and father of Rafferty, 8; Iris, 4; and Rudy, 2, with ex-wife Sadie Frost, 40. "It's very hard when you have to live out your life and your mistakes in public."
