Kate Walsh and Balthazar Getty, neither of whom have had much luck with marriage lately, cuddle up at the Oliver Peoples Hollywood luncheon yesterday in LA.

But my favorite thing about this photo?

The little scrunched-up bulges in Balthazar’s pants.

What did Wendie call that again?

Oh, yes. An ass twat.

America hates him, the U.K. hates him, and it looks like the producers of his hit TV show, Brothers & Sisters, feel the same way. The filthy womanizer, who left his wife alone with a newborn baby while he frolicked around the world with Sienna Miller, is being written out of the series ASAP, say sources.

According to sources who work on the fan-favorite ABC drama, the show’s writers and producers have rewritten certain scenes and storylines in order to phase out Balthazar Getty, who plays Tommy Walker, before the current season ends.

“Episode 19 is expected to be his last,” one well-placed insider tells us.

Getty’s rep says “not true.” The show’s rep declined comment.

Ewww, good for them. This guy is so gross and selfish. I hope this is the last we see of this creepazoid.

Despite the fact that EVERYONE hates Balthazar Getty’s relationship with Sienna Miller — and the tension it’s causing on the set of Brothers & Sisters has Balthazar’s job in jeopardy! — the two are still out and about together. They were caught this week canoodling in Mexico City while trying to hide from the paparazzi.

If you feel like you have to hide what you’re doing, don’t do it!!!

Hey, guys. You know how you hate Balthazar Getty? Because he left his wife and four young children to frolic naked on beaches around the world with Sienna Miller? And that shit’s just appalling? Well, turns out everyone on the set of his TV show, Brothers & Sisters, hates him, too.

“No one on set is a fan,” one source reports.

How bad is it?

I’m told Getty has been late to set and he’s been in foul moods. “They often have to move shooting schedules around to accommodate [him],” a source says.

Getty was so “difficult” on Monday that one costar was reduced to tears, according to the sources.

When shooting was delayed, he appeared to become impatient. According to a source, he barked, “When are we going to shoot this?”

When they did start filming, Getty was “forgetting his lines,” a source says.

Getty began losing friends at work back in July when it was revealed he had left his wife and the mother of his four children, Rosetta, for Sienna Miller. To make matters worse, before they hooked up, Miller happened to have dated one of Getty’s pals, his Brothers & Sisters costar Matthew Rhys.

Cast and crew first worried about Getty’s questionable behavior shortly after his and Miller’s romance took off.

But now they’ve had it.

“It’s bad,” one of the sources says. “It’s just so sad.”

Seriously — what was this guy thinking??? How could you not hate him after the shit he pulled?

Sienna Miller has officially confirmed her split with Balthazar Getty.

“I’m single at the moment, and I’m completely happy with that,” she said Friday at the Hollywood Dominoes: VIP Launch in London. “It’s nice not to have a relationship that the press constantly want to scrutinize and discuss. I’m cool with being on my own.

My money is on Rosetta, Getty’s wife, getting her man back.  A wife and four children should be a bigger pull than a trick pelvis.  Though I never think staying together for the sole sake of kids is a good idea, I do think children can be a great motivating force for adults to find a way back to happiness.  I wish them luck!  And I actually wish Sienna luck too!

Well it’s coming from The Daily Mail so take it with a grain of salt.  But apparently Sienna Miller has moved back to London to get some space from her married, live-in boyfriend Balthazar Getty.  He has made no motion to file for divorce from his wife of 8 years and Sienna doesn’t like that.  He cheated on his wife with Miller and now she’s upset that he won’t commit.  I love irony.  I, too, hated when my old boyfriend’s wife got in the way.  Selfish bitch.

But wait, there’s more.  Getty is a recovering alcoholic and drug addict and Sienna is rumored to be…you know, the same minus the “recovering”. 

If you could create an instruction manual on how to craft a doomed for failure relationship, wouldn’t these two be in every diagram?

Sienna Miller looks a little uncomfortable as she leaves the Groucho club in London — along with married flame Balthazar Getty, who was careful to keep his back to the photogs.

Really, Sienna, must you do this publicly?

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!!!
