Sienna Miller didn’t end Balthazar Getty’s marriage, claims source

Sienna Miller’s relationship with Balthazar Getty didn’t end his marriage, a new source has claimed.

Balthazar’s wife Rosetta is said to have fled to Italy with the couple’s four children after Sienna and Balthazar’s relationship hit the public eye - but a source close to the Brothers & Sisters actor insists their marriage was over before Sienna appeared on the scene.

The source explained: “Sienna is not a homewrecker. It’s been over with him and his wife for some time. I believe he’ll be making an announcement shortly.”

Sienna is said to have spent most of June bunkered down with Balthazar in his Los Angeles home after being introduced through their co-star - in The Edge of Love and Brothers & Sisters respectively - Matthew Rhys earlier in the year.

Earlier this month, they were spotted together in Prague then last week, kissing on a yacht moored off the Amalfi coast in the Italian riveria.
