Miller splits from Balthazar Getty

Sienna Miller has split up with her boyfriend Balthazar Getty, according to reports.

The actress has decided to end her romance with the Brothers & Sisters star after tiring from the on-again/off-again relationship, says The Mirror.

"Sienna loved being with Balthazar, but there was too much baggage and she couldn't commit to anything more than a few months. They are still good friends," said a source.

Miller is now understood to be "getting more and more friendly" with Josh Hartnett, who she rushed to visit in LA last month after he'd been admitted to hospital for severe stomach pains.

"Josh and Sienna have a unique bond. They understand each other and I wouldn't be surprised if a relationship blossomed," the source added.
