In the wake of Balthazar Getty's announcement that he and his wife Rosetta have separated, friends say Rosetta was "blindsided" by her husband's affair with Sienna Miller.

The Brothers & Sisters star announced that he and Rosetta, 38, had separated in a statement released Monday. The announcement came after photos revealed Getty, 33 and Miller, 26, cavorting in Italy, including many of her topless.

Now pals are bristling over comments from Getty's camp suggesting that he and Rosetta had been living separate lives for some time before his relationship with Miller became public.

"Balthazar and Rosetta were in no way separated when Balthazar began his relationship with Sienna Miller, and any implication otherwise is an absolute lie," says a close friend of the couple. "Balthazar's affair has been utterly devastating to Rosetta and her family."

Sources close to Rosetta – who last year launched high-end women's clothing line Riser Goodwyn – insist the separation Getty mentioned in his statement is not legal. They say Rosetta, 38, has been "blindsided," and learned of the tryst not long before the pair were photographed kissing on Italy's Amalfi coast.

Earlier this month the couple reunited in L.A. for son Cassius's eighth birthday. "Rosetta felt it was important that the whole family be there," says another friend. "They made it as comfortable as possible for Cassius, but it was extremely uncomfortable for her."

The Gettys married in 2000 and have four children, the youngest 9-month-old June Catherine.
