Sienna Miller's very public romance with married hunk Balthazar Getty has "humiliated" his wife Rosetta, reports People. A friend tells the mag, "Rosetta left the country to protect the kids, and he continues to see Sienna publicly."
Sienna, who broke it off with Welsh actor Rhys Ifans just weeks ago, has recently been photographed frolicking on a boat with Getty -- topless. She's also been spotted canoodling on a balcony, similarly unclad.
Getty and his wife have reportedly been "living separate lives for a while," according to People. They were married in 2000 and have four kids together -- the most recent child born just 10 months ago. Getty's great-grandfather was oil billionaire J. Paul Getty.
