Sienna Miller 'dates married man'

Sienna Miller has reportedly found love with a married man following her split from Welsh actor Rhys Ifans.

According to the News of the World, the actress has been secretly romancing oil heir and actor Balthazar Getty, a father of four, after they were introduced by Sienna's Edge of Love co-star Matthew Rhys.

News of the couple's affair has left Getty's wife Rosetta "devastated". She has now fled to Italy with their children, one of whom is just eight months old.

A source told the newspaper: "Sienna got to know Balthazar through Matthew and they hit it off. In the past three months they have grown incredibly close. Getty even secretly flew to London and Prague to be with Sienna to get to know her even better. And she's spent this week in a Hollywood house with him.

"Even though Balthazar loves his wife and children he cannot stay away from her. But Rosetta found out about them and has now fled to Italy. She can't believe her husband could do this to her. The whole family now know and everybody is devastated."

Getty, who stars with Matthew in US drama Brothers & Sisters, is the heir to the fortune of his great-grandfather Jean Paul Getty, founder of the Getty Oil Company.

Miller split from Ifans at the beginning of this month. He is said to be "inconsolable".
