Sienna Miller's Heartache At Getty Split

British actress Sienna Miller is "devastated" after her alleged lover Balthazar Getty returned to his wife in a bid to save his marriage.

The Brothers + Sisters star, 33, confirmed he had split from his wife Rosetta after photos emerged of him frolicking with a topless Miller on a yacht off Italy's Amalfi coast last month (Jul08).

But according to British newspaper The Daily Mail, Getty has returned to his wife and mother of his four kids, leaving Miller heartbroken.

A source tells the publication, "He... was on the phone to Rosetta on and off for two hours, crying and constantly calling and she finally agreed to let him back in the house.

"In his mind he has definitely dropped Sienna but he's in a very confused state at the moment. His biggest fear is losing his kids."

Getty says, "I can't comment. When I'm ready, I'll issue a statement. It's because of the children.'"

A spokesman for Miller has refused to address the reports.
