You know that chick in high school who poached all the other girls’ BFs, then wondered why they hated her guts? Ever wonder what happened to her? Well, she grew up to be Sienna Miller.

After finally noticing she had no female friends, Sienna groused to the London Mirror, “I’ve been at war, without a doubt. I’ve really experienced the judgment of women in the past year. We say we want to be equal, but men don’t sit around bitching at each other. There’s no sisterhood.”

Oh gee, wonder why? Maybe because you’re a homewrecker? Because you’ve been having a public affair with a married man who has kids at home? Could that be it? She should consider herself lucky that “judging” is all they’re doing. If this was still high shcool, they’d be dragging her out behind the gym and beating the crap out of her.

Get used to it, Sienna. Other women won’t be inviting you over to the house for dinner when you’re likely to drag their husbands upstairs between the dessert and coffee.

This fall, Sienna Miller will be making her Broadway debut in Roundabout Theatre Company’s production of “After Miss Julie.” AP reports that Miller will take the title role, a wealthy young woman who becomes falls in love with a family manservant.

Since her married lover Balthazar Getty is getting canned from the series “Brothers & Sisters,” he should have lots of time to hang around NYC and keep her from taking up with someone else.

Adulterous lovers Sienna Miller and Balthazar Getty spent Thanksgiving together in London after a few weeks apart but on his return to LAX, Getty insisted the two had never broken up. He told waiting photographers:

“A quote that came out the other day about her saying we split up was a quote they plucked out of thin air. It was bulls–t.”

He seems to have forgotten that Sienna stated very publicly that she was “happily single” at a party in London recently. And was also seen getting very cozy with another actor. No word on how Getty’s wife and four children spent their Thanksgiving.

Just when it looked like Balthazar Getty had done the smart thing and dumped hard-partying actress Sienna Miller to reconcile with his wife and four kids, he’s fallen back under her spell. The UK Sun is reporting that instead of spending Thanksgiving with his family, Getty was spotted in London with Miller. The pair started the day by walking their dogs in Maida Vale, then had a meal at  San Lorenzo in Knightsbridge and finished the evening at 2:30 am at the Groucho Club. Too bad Getty can’t put his kids ahead of his mistress for one day.

Less than a month after her adulterous affair with father-of-four Balthazar Getty hit the rocks, Sienna Miller has rebounded into the arms of another actor. The London Paper is reporting Miller had an intimate date with Josh Hartnett at the exclusive Shoreditch House in East London. A source reported:

“They definitely looked like a couple—and a good looking one at that! At one point, they were holding hands across the table, but they quickly hid them underneath. They looked really cozy as they dined, gazing into each other’s eyes, smiling and laughing. They continued talking and drinking until very late into the evening – there was definitely a buzz in the air.”

Wonder how long Josh can hold her interest when she didn’t have the challenge of stealing him from someone else?    

It’s official—Sienna Miller’s efforts to break up Balthazar Getty’s marriage have failed and she’s on the prowl again. Sienna confirmed her split from the married father of four to Us Magazine at a charity event in London.

“I’m single at the moment and I’m completely happy with that. 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.”

Yeah, sure. Let’s see how long it takes before she finds another married man to steal.

Sienna Miller has returned to London—and her hard-partying lifestyle—amid reports that her adulterous affair with actor and married father of four Balthazar Getty is finished. According to a aource:

“Sienna is back in London to give them both some cooling-off time. They are still together at the moment  but she has said things aren’t good. There have been some pretty unpleasant rows, largely over Balthazar’s reluctance to commit. She has really wanted to be able to step out as a couple but Balthazar is very torn over his children and it looks like he might be wanting to go back to his family. Sienna is devastated.”

It’s also reported that SIenna likes to go out drinking and partying all night while Balthazar, a recovering alcoholic and drug addict, prefers quiet evenings with friends. Hmm—why does this not sound like a match made in Heaven?

Sienna Miller continues to take the paparazzi onslaught because of her affair with married Balthazar Getty alone. I’m actually starting to feel sad for this girl. Don’t get me wrong now, she shouldn’t have messed with another woman’s man, but he should be getting beat up just as bad as Sienna is. She took such a verbal beating from the paps yesterday as she left a Beverly Hills clinic, I wouldn’t be surprised if she bounces back to the U.K. any second now. Unless she really does believe that their love will conquer all.

So here’s Sienna Miller leaving a Pilates studio in West Hollywood yesterday and from the looks of it, she may very well be starting to feel the shame of being the worlds most famous home wrecker. I don’t know, what do you guys think? I know we haven’t talked about it much but where the hell is Balthazar in all this? I think he should be standing right there next to Sienna in all these pictures hanging his head in shame just like her.

Photos have surfaced on the internet recently of married actor Balthazar Getty kissing a topless Sienna Miller in Italy, and they’re now getting some (much deserved) flack for it. According to People.com, Sienna met Balthazar through his Brothers & Sisters co-star, Matthew Rhys. Matthew was said to be livid when he saw pictures of Sienna and Balty all over each other, since he and Sienna also had a brief fling a while back. Meanwhile Balthazar’s wife, Rosetta, is said to be extremely embarrassed by her husband’s very public infidelity show. And who can blame her, right? “It’s humiliating,” a friend of hers told People. “Rosetta left the country to protect the kids, and he continues to see Sienna publicly.” Rosetta and Balty have four kids together and have been married since 2000. Sienna, meanwhile, just broke up with actor Rhys Ifans only a few weeks ago, although sources told People that Sienna and Balty have been seeing each other “quietly” for a couple of months now. Hmm, I think it’s probably time for Rosetta to file those divorce papers right about…now.

We were on location at the G.I. Joe set yesterday and our photogs even weathered the pouring rain just to get you great pictures and a video. A lot of ’80s children are going to be excited about this movie. I know I am. It’s not just guys that watched G.I. Joe religiously and played with the action figures. Anyway, I have some pics of Sienna filming that funeral scene, but I also have pics of her taking a little break on Duke’s motorcycle. Enjoy.

I know there are alot of G.I. Joe faithfuls out there, including me, so I’m excited to bring you your first look of Sienna Miller as The Baroness on the Los Angeles set of G.I. Joe. The Baroness is a brunette character which might change later on in the movie so all you purists out there, don’t go crazy just yet.

So those of not wanting to be spoiled, turn back now as we’re going to be giving out some details from the scene.

For spoilers, click below…

So the scene is a funeral in which Sienna is given an American Flag. Notice the rifle in the ground with the hat hanging on it as well as the pair of military boots. There is an Army flag and even though it’s been raining on and off throughout the day, rain is being dropped on the scene. I’ve got a ton more pictures and video coming but I figured you guys would want to see this sooner than later.

Sienna Miller arrived at LAX last night amid a horde of paparazzi and well, she wasn’t very happy to see her photog welcoming committee. From the sounds of it, photographers were just as happy to see her as she was to them from the reaction she got.

Our favorite American-born English actress, Sienna Miller, arrived in Los Angeles last night. Our hard working photographers caught up with her at LAX. Sienna’s not a big fan of paparazzis (or the city of Pittsburgh, for that matter), but they still love taking pics of her anyway. Sienna has a few movies coming out in 2008, including The Edge of Love and A Woman of No Importance. For those keeping up with Sienna’s love life, she’s currently dating Welsh actor Rhys Ifans. Rhys was the guy who played Hugh Grant’s crazy roommate in Notting Hill. Hmm, that might not be a good movie to reference. I read somewhere that Rhys really wants to get serious (like marriage serious) with Sienna, but she’s not too keen on it. I believe it. She’s a young woman and she probably wants to chill out for a bit. Whatever the case is with her love life, we have more pics of her walking around LAX like a trooper. Enjoy the shots.
