Poor Sienna Miller. She’s gotten so used to wearing her TJ Maxx leggings and ratty old t-shirts that she’s forgotten how to carry herself in an evening gown. While attending the Metropolitan Opera in New York recently, Sienna arrived with her lovely dress in one piece. But by the time she was leaving, she was lucky it was still hanging onto her body. Apparently, either she or someone else stepped on the dress and ripped the skirt away from the bodice. Maybe next time she’ll remember to hold up her dress when she walks, or better yet, get it hemmed by a tailor to fit her petite frame.

Jude Law, Sienna Miller, and Sienna’s mother, (who some commentors on the JJB board think looks like Fergie) attended the opening of the Metropolitan Opera in New York last night. Sienna’s fake hair seemed almost natural, and although her dress didn’t fit quite right she looked surprisingly good. Does this mean that Jude and Sienna are back together this week? Probably, but I stopped caring long ago.

Sky Showbiz notes that Jude and Sienna were careful not to be photographed together, and posed with Sienna’s mother in between them. It doesn’t seem like they’re being that sneaky to me if they all went out together and were willingly photographed.

Sienna’s performance as Andy Warhol’s muse Edie Sedgwick in “Factory Girl” is said to be Oscar worthy and could help cement the 24 year-old’s acting career:

We’ll see what happens for Sienna. It’s going to be an interesting Oscar season if both Sienna Miller and Ben Affleck are nominated.

Kate Moss is now dating Jamie Dornan, the British Wilmer Valderrama. His acting career hasn’t taken off yet, but somehow he’s managed to hook up with plenty of starlets. In case you’re not familiar with Jamie Dornan, he dated Knightly Knightly on and off for about two years. The two split up in August of 2005 amid allegations that Dornan was jealous of Knightly’s career. Dornan’s only credited film on IMDB is the upcoming “Marie Antoinette.”

Dornan has been keeping busy off screen:

Sienna Miller is taking herbal breast enhancement pills in a bid to increase her cleavage.

A friend of mine took those things a couple of years ago, and claimed they actually worked. She said they made her ass bigger too, though. At least she’s trying to do it naturally instead of opting for the surgical route right away.

Sienna will design her own jeans as part of her deal with Pepe. It’s a good thing that she’s limited to jeans and can’t do damage with a full fashion line. Remember how she said she would never design her own clothing line? Guess she considers this an exception.

Here she is at the Costume Institute Gala yesterday. Her hair is a mess. Has she ever looked polished and presentable?

The Costume Institute Gala at the Metropolitan Museum of Art held a ball last night to celebrate the opening of an exhibit on British design. Sienna Miller, wearing an awful gold sequined minidress and black tights, served as co-chair for the event.

The guy dressed like a cabaret pirate posing with Charlize Theron is Dior designer John Galiano. He’s responsible for her monstrosity of an Oscar gown with the giant shoulder bow. Sienna Miller is shown with Christopher Bailey, Burberry’s creative director.

We have over 100 pictures from the event.

At the beginning of the month Sienna Miller was said to be dating Jamie Dornan, Keira Knightly’s ex. A week or so later Jude Law flew to NY to be with Sienna, and Jamie Dornan was supposedly with Lindsay Lohan. Sienna then had a Mexican vacation with hot model Nico Malleville like a day or two after she reunited with Jude. We haven’t even mentioned Sienna’s relationship with her Factory Girl costar Hayden Christensen, who she was dating at the end of January.

This is like the third or fourth reconciliation for Jude and Sienna, and it’s pretty hard to keep up.

Anyway Jude just had a vacation in California with his ex and three kids, during which he accused a photographer of pedophilia for taking pictures of his children. And Sienna has struck out at the paparazzi several times herself, so it’s not surprising to see both stars looking mighty grumpy in these candids of them out with Jude’s kids and older nanny. They all went to see Ice Age 2 and had to get a police escort to stave off photographers:

Here are the pictures of their outing, courtesy of Just Jared.

We dug around for these pictures of the new guy that Sienna Miller is supposedly seeing, Nico Malleville. Nico is an Argentinian-born model who has appeared in ads for DKNY and Burberry, and who owns several hotels. He might not be dumb, but he has to have something wrong with him in order to hookup with Sienna.

Supposedly they met a few years ago and spent a vacation in Mexico together just two weeks ago:

Now the timeline is incredibly suspect - because Sienna was said to have spent a few days with her ex Jude Law on Wednesday, April 5th, which is a little over two weeks ago. That means that Sienna is working two men and barely took a break between them.

Update: Pictures of Sienna Miller at club MisShapes on April 15th. Note that the club is in New York, and that Sienna is smoking. Smoking in clubs has been outlawed in New York for several years. [via]

Sienna Miller’s new extensions look terrible, and she’s a total mess. The girl needs to get a stylist right away. Even one of those anorexic blonde boho stylists would do a better job at dressing her than she does herself. Hell, a random person on the street could probably pick out a better look for the actress.

The only recent news about Miller involves a mystery guy she supposedly had a date with, and the fact that she made an ass of herself at the Oscar parties, which we already reported.

Here she is in NY yesterday wearing sunglasses she could have replaced with a more stylish pair off the street. She is also seen on Monday wearing paint-splattered boots and running into Susan Sarandon. [via]

Just like Jessica Simpson, Sienna Miller has been spotted out in the wrong brand of jeans when she’s contractually obligated to wear a certain brand:

Oops. Guess a fashion contract means that you can’t even go out of your house wearing clothes that aren’t sponsor-approved. It’s not as big a sponsor faux pas as Jessica Simpson made, though. According to a new lawsuit against her, she named “True Religion” as her favorite brand of jeans when she was supposed to promote a line named after her creepy father’s nickname for her, “Princy.”

Here is Miller on the set of “Interview,” in which she plays a soap actress who gets interviewed by a “fading political journalist” played by Steve Buscemi. Hillary Duff is shown in the same dress as a host of the 2005 Teen Choice Awards. Via ONTD!.

Jude and Sienna are said to be together yet again. They are probably just seeking each other out since they’re both free. Jude was back with his ex wife Sadie Frost according to our active imagination, and Sienna was supposedly romancing Keira Knightly’s ex, British actor Jamie Dornan. Those relationships must not have worked out since no one will put up with either of these sloppy actors, so they’re running back to each other.

Britian’s The Mirror reports that Law flew to NY to be by Sienna’s side on Wednesday, and returned to London’s Heathrow on Saturday. (Maybe he just couldn’t resist her new ratty hair.)

Jude is supposed to be in Malibu soon for a pre-planned vacation with his ex-wife and three children. This can only enrage Sienna, who accused Jude of “playing house” with his wife the last time they split. Maybe she’ll hold her tongue for a week or so until the next round of fighting begins.

In related news, Sienna needs to lay off the drinking while she’s out at the Oscar parties. She must not have read the NY Times article about proper Oscar party etiquette, because she’s been blasted for her stupid, drunken behavior, and there are pictures supposedly:

We can’t wait to see those pictures! Maybe they’ll help law think with his head instead of his tiny peter.

Here is Law having dinner with friends in London on April 5th.
