Sienna Miller Splits From Married Balthazar Getty

Sienna Miller and Balthazar Getty have split, the actress tells Usmagazine.com.

"I'm single at the moment, and I'm completely happy with that," she said Friday at the Hollywood Dominoes: VIP Launch in London. "It's nice not to have a relationship that the press constantly want to scrutinize and discuss. I'm cool with being on my own."

Miller and Getty's romance first made headlines in July when Getty, 33 -- who was married at the time -- was photographed kissing a topless Miller, 26, on a boat in Italy. (Miller later sued two British newspapers and a photo agency for breach of privacy for publishing the steamy shots.)

On July 21, the Brothers & Sisters star announced that he and wife Rosetta (with whom he has four children) were separated.
