Balthazar Getty Continues to Flaunt his Affair with Sienna Miller

(andPOP) - Although still married, Balthazar Getty isn’t afraid to hide his steamy affair with actress Sienna Miller, reports People magazine.

The "Brothers & Sisters" actor was spotted making out with the barely clad actress on a boat off the Amalfi coast.

Miller may have broken up with actor Rhys Ifans only a few weeks ago but, according to a source, Getty and Miller have been dating quietly “for at least two months.”

Getty, who has his wife’s name tattooed on his chest, married Rosetta in May 2000. The couple had their fourth child together 10 months ago. Although a source tells People that the couple “have been living separate lives for a while” the entire affair is a lot to handle for Getty’s wife.

“It's humiliating,” a friend of Rosetta’s tells the magazine. “Rosetta left the country to protect the kids, and he continues to see Sienna publicly.”
