I’m driving myself crazy trying to think up a cutesy nickname for these two.

Sienazar? Balthienna? The Homewrecking Assholes? I dunno. I like the last one.

The Homewrecking Assholes have finally put an end to their frolicking on the beach. Now they’re frolicking on the New York social scene instead. On Thursday, they hit up an art show at the South Street Seaport and later hung out at the Rose Bar.

Conspicuously absent?

Balthazar’s 10-month-old baby, whose mother he ditched for Sienna.

So very, very sad.

“The breakdown of a marriage is a very difficult and painful experience especially when children are involved,” Balthazar Getty said in a statement released Monday. “In light of the fact that many pictures have surfaced in print and on the Internet which has caused myself and my family great embarrassment, I felt it necessary to at least acknowledge publicly that yes indeed my wife and I have separated and I will not be commenting any further.”

Life is so tragic when you’re sucking on Sienna Miller’s tits on a beach all day.

Tragic indeed.

If you can believe it, the wife of billionaire Balthazar Getty is less than thrilled that he’s taken up with Sienna Miller, frolicking around naked with the starlet every chance he gets.

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

The couple were married in 2000, and have four kids together. The youngest is 10 months old.

SCANDALOUS!!!
