Yesterday, Sienna Miller’s friends came rushing to her defense, saying that the bed-hopping actress is not a homewrecker. But the wife of Balthazar Getty, the actor/millionaire Sienna is currently banging, might have a different opinion. Rosetta Getty, whose name is tattooed on her cheater husband’s chest, is said to be devastated by recent photos of Balthazar and Sienna frolicking half naked together. She’s been humiliated enough to take her children and leave the country to protect them from the media.

Sienna Miller’s steamy affair – and much of her body – has been exposed now that the barely clad actress has been spotted kissing married Balthazar Getty in a boat off the Amalfi coast.

Miller, who had a roller-coaster relationship with Jude Law and broke up with actor Rhys Ifans only weeks ago, has been quietly dating Getty for “at least two months,” said a source.

Miller, sporting a sailor’s cap, was also spotted topless on the balcony of an Italian hotel room kissing Getty. Meanwhile, the Brothers & Sisters actor, 33, and his wife Rosetta “have been living separate lives for a while,” a source tells PEOPLE.

Getty, who has a tattoo of his wife’s name on his chest, married Rosetta in May 2000. They had their fourth child together 10 months ago.

“It’s humiliating,” a friend tells PEOPLE. “Rosetta left the country to protect the kids, and he continues to see Sienna publicly.”

The two met through Getty’s Brothers & Sisters costar Matthew Rhys. Rhys, who briefly hooked up with Miller, was livid when the photos of the couple surfaced, says a source.

So, let’s tally up the number of people Sienna and Balthazar have managed to alienate. First, there’s Balthy boy’s wife and four children. Even if the couple have been living “separate lives for some time”- and really, how separate could their lives have been if they had a baby less than a year ago?- getting caught in photos like the ones circulating this week are inexcusable. Then there’s Sienna’s jilted fiance, actor Rhys Ifans, whom she dumped over the phone just a few weeks ago- which means she was already humping around with Balth by then. And finally, there’s Getty’s co-star, Matthew Rhys, who was foolish enough to introduce Miller to his richer co-star and think that she wouldn’t spread her legs at the drop of a hat. That’s seven people, folks. That’s a whole lot of bad karma coming their way. Personally, I can’t wait.

Sienna Miller must pay her friends really well. Or – more likely – reward them with the occasional flashing. All of her nearest and dearest have been flocking to the weekly magazines and tabloids to proclaim Miller’s complete and utter innocence in her affair with married father of four Balthazar Getty. Getty’s wife of eight years, Rosetta, has been reported to be absolutely heartbroken by the affair. But Miller’s friends are claiming the Getty marriage was over long before Sienna ever came into the picture.

In fact, she and Getty are said to have been living together in L.A. for over a month. Sources say he even rode his bike to meet her for dinner at one restaurant, lest they be seen together.

Despite the subterfuge, one friend of the couple tells us Getty’s marriage was on the rocks long before Sienna entered the picture.

“Sienna didn’t break up his marriage,” says the friend. “It’s been in trouble for a year. The truth is, they’ve quietly separated.”

Miller knows something about heartache. A few years back, ex-boyfriend Jude Law cheated on her with nanny Daisy Wright.

I call hogwash on every word. Unlike a lot of people I don’t think Sienna Miller is totally evil. But I think she’s overrated, and probably deserves a good deal of the reputation she has. Miller’s friend also went on to say that she never really had feelings beyond deep-friendship for her heartbroken ex-fiancé, Rhys Ifans. Miller broke up with him over the phone.

I think Sienna is the female John Mayer. No offense to any Mayer fans. She goes through people like candy, and doesn’t seem to give a thought to how it affects anyone but herself. Considering she was cheated on, it makes it extra sad that she couldn’t empathize with Balthazar Getty’s wife and children and keep her crotch to herself.

Sienna Miller is now in Positano, Italy with her married boyfriend, the actor and oil heir Balthazar Getty. Miller, 26, and father of four Getty, 33, were photographed kissing on a boat on Saturday. Miller was topless and wearing only her bikini bottoms. The two also enjoyed lunch on the balcony of their hotel in Italy. Getty was wearing a shirt but Miller apparently forgot hers again. You can see those photos at Mr. Paparazzi’s site.

There’s a new interview in the British version of OK! Magazine with Miller. She was asked to name the worst thing she’s seen written about herself, and she said that Perez Hilton scrawled the word “slutty” over a picture of her visiting her grandparents’ grave:

What’s the worst thing you’ve seen written about yourself…
Oh God. I went to see my grandparents’ grave with my father and they took a photo of us sitting. Above Miller on the tombstone [Perez Hilton, internet blogger] wrote ’slutty.’ I just thought that was unbelievably tacky. That was a weird place to be papped. There are times when you have no idea someone is there and then suddenly there’s a photo and that is always a bit weird.

She also repeated the claim that I’ve heard her go on about before that the media attention takes away from the public’s perception of her acting ability. She said essentially the same thing in an interview with The Times in June. She also brought up the war and starving people as if we’re the ones being heartless by paying attention to her. And then Miller says that hopefully the public will stop noticing all the crap she gets up to with married men and be awed by her acting ability instead:

Do you feel you’re treated unfairly by the media?
They don’t want me to be a good actress, they want me to be what they say that I am, which is actually very far from the truth. But at the end of the day it’s not a big deal. I mean, there’s a war on, people are starving, we live on a little island and it’s not important.

But still it’s your private life everyone wants to know about…
I think with time.. All I can do is focus on work and try to do a good job. Hopefully, eventually that will supersede the other less meaningful aspects of my life, but it’s a process, you know. It’s a battle.

[From OK! Magazine, UK print edition, July 15, 2008]

Yeah, it’s a battle for sure for Sienna, and she’s throwing in the towel by going on vacation with a married guy and whipping her top off every chance she gets. She’s calling the fact that she’s cavorting topless with a married man “a less meaningful aspect” of her life when compared to her acting. I bet his wife doesn’t feel that way. Somehow Sienna seems to bring the slut with her wherever she goes, whether it’s tacky or not to point it out.

I looked through Perez’s site for about five minutes and couldn’t find the photo in question, so if you have a direct link for that slutty cemetery pic please comment with it.

Sienna Miller seems intent on carrying on her string of bad relationship decisions. The actress has taken up with married father of four Balthazar Getty, an actor on the ABC show Brothers and Sisters. They were introduced to each other last summer, and started spending a good deal of time with each other at the Chateau Marmont in March and April. News of the World has a very detailed account of the pair’s relationship, including what appears to be a day-by-day near stalking of the couple, along with pictures.

Sexy Brit actress Sienna Miller is secretly on the Edge Of Love with a married multi-millionaire oil heir, we can reveal. The rampant movie beauty has been enjoying romantic nights with tycoon actor and dad-of-four Balthazar Getty after dumping heartbroken Notting Hill star Rhys Ifans earlier this month. The besotted pair have been holed up together day and night in Hollywood after his heartbroken wife fled the country with their kids.

Despite playing a cat and mouse game to stay out of the headlines they have been spotted secretly meeting at restaurants near their hillside hideaway. A source revealed: “They went to great pains to find a place where they thought nobody would find them. They daren’t go out together, so they spend most of their time inside. When they do leave, they go separately.”

In one rendezvous on Thursday, 26-year-old Sienna drove to a restaurant while former heroin addict Getty, 33, even cycled there to try to avoid being spotted with her. Now Getty’s clothes designer wife Rosetta has run away to Italy with their four children —the youngest born only eight months ago—after rumbling her wandering husband.

And pals say lovestruck Sienna has even used her ex-boyfriend and Edge Of Love co-star Matthew Rhys as a smokescreen for their romance… trying to give the impression she might be back with HIM after her split from 39-year-old Ifans.

[From News of the World]

I have no idea what “rumbling” means in this context, but it can’t be good. Even though it made me giggle. Thank heavens for ever-evolving British slang. Supposedly Sienna broke up with ex-boyfriend Rhys Ifans because she wanted to “do the right thing” before stuff went further with Balthazar. Apparently the right thing only has to do with her relationship, and not Getty’s wife or four kids.

What a seedy situation. You can check out the News of the Word’s play-by-play of the couple’s secret relationship. The Huffington Post picked up the story as well, so it sounds like it’s pretty legit. Sienna Miller makes such poor relationship choices. Rhys Ifans seemed to be a notable exception. He was head over heels for her, and it was absolutely adorable. She seems like someone who will have to repeat her mistakes a couple times before she learns the lesson… if she can learn it.
