Sienna Miller and Balthazar Getty's Hurtful Romance

Sienna Miller ’s steamy love affair and most of her body was exposed just a week ago on the balcony of an Italian hotel room, where she was spotted kissing “Brothers & Sisters” stud Balthazar Getty.

And Balthazar's wife, Rosetta (whom he has been married to since 2000), is mortified by her husband’s behavior - with a friend telling press: "It's humiliating. Rosetta left the country to protect the kids, and he continues to see Sienna publicly."

As previously reported by Gossip Girls, the scantily clad "Alfie" actress, 26, was topless and wearing only a sailor’s cap while also being spotted canoodling with Getty, 33, in a boat off the Amalfi coast.

Sienna, who ended her high profile rollercoaster relationship with her actor hubby Jude Law in 2006, just recently broken it off with boyfriend Rhys Ifans, but sources say she has been secretly seeing Getty for “at least two months”.

According to past reports, Miller and Getty met through Getty’s “Brothers & Sisters” co-star Matthew Rhys - whom Miller dated briefly. Rhys was said to be “livid” when the photos of the pair surfaced.

Insiders have added that Getty and his wife Rosetta “have been living separate lives for awhile.”
