Balthazar Getty's Wife ‘Humiliated' By Sienna Miller

Sienna Miller's steamy (and now public) affair Balthazar Getty has been going seeing each other for at least at least two months, reports People.

But the 33-year-old Brothers & Sisters actor and his wife Rosetta 'have been living separate lives for a while,' a source reveals to the mag.

Balthazar, who still has a tattoo of his wife's name on his chest, married Rosetta in May 2000 and have four children together: Cassius, 8, Grace, 7, Violet, 4, and June, 10 months.

'It's humiliating,' a friend admits. 'Rosetta left the country to protect the kids, and he continues to see Sienna publicly.'
