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.

Younger members of the in crowd picked up lots of swag at the “Desert Oasis” Coachella invite-only party held in La Quinta, California on Saturday at Frank Sinatra’s Twin Palms estate:

Hopefully Nicole Richie got some free sunglasses. The ones she wore to the party look like they came from a joke shop.

Pictured attendees include Taryn Manning, Nicole Richie, Nicky Hilton, Kevin Connelly, Scott Speedman, Busy Phillipps, Alex Nesic, and Melissa Sagemiller.

Paris Hilton is getting paid half a million dollars to host a rock concert this weekend in Austria. I would work 60 hour weeks for two years straight for that kind of money and consider myself lucky as hell.

Her idea of working hard is seriously skewed. Her house is enviable though, of course.

In the pictures of Paris’ Hollywood villa below that were published in Hello Magazine, you can get a sense of the “Old Hollywood” style favored by her interior designer, and see the chandeliers hanging in her closet and over her bed. She also has a huge picture of herself hanging in her lounge.

Among her memorable quotes in the article accompanying the pictures:

Us Weekly’s Hot Hollywood Awards were held Wednesday night. Jessica Alba had a near nip-slip that resulted in some cute picture of her pulling her dress strap up. (Wireimage did not capture this, so you’ll have to see it everywhere else.)

Despite Us Weekly’s content, stars were pleased to show up for the party.

We have over 50 pictures of the party arrivals, including Jennifer Love Hewitt, Jessica Alba, Alessandra Ambrosio, Brittany Murphy, Cindy Margolis, Garcelle Beauvais-Nilon, Ludacris, Harry Hamlin, Lisa Rinna, Haylie Duff, Jamie-Lynn Sigler, Paris Hilton, Victoria Silvstedt, Avril Lavigne, Carmen Electra, Dave Navarro, Michelle Trachtenberg, Rachael Leigh Cook, Nicky Hilton, Gabrielle Union, Kelly Osbourne, Kimberly Stewart, Stacy Keibler, Ryan Seacrest, Sofia Vergara, Taryn Manning, Maria Sharapova, Melinda Clarke, Tom Green with a fanny pack, and Tori Spelling.

Update: Images removed on request.

Maybe Paris Hilton can act. According to the Swedish newspaper, Aftonbladet, the hard-partying heiress cried to get out of a ticket for driving without a registration for her new car:

So Paris didn’t even get a ticket for driving with an unregistered vehicle. She’s had the car for about a month, so you think she could send one of her minions to the DMV for her. Here are some pictures of Paris getting a parking ticket, so she’s at least suffered that indignity.

Here’s a German commercial for online yellow pages featuring Paris ordering some rolls:

And here are pictures of Paris celebrating her boyfriend Stavros Niarchos III’s 21st Birthday Party at Tao Night Club in Las Vegas on 4/22. [via]

Update: pictures of Hilton at the opening of the “replay” clothing store in LA last night. Brandon Davis is launching his line of jeans at the new store. Davis is a former friend of Hilton, and spoke out against her last year, calling her a racist. Nick Hilton also attending the opening.

Paris will host a rock concert at an Austrian ski resort this weekend, and will have to introduce Pink to the crowd. Pink mocks the skinny heiress in her video “Stupid Girls.”

TMZ reported that Britney Spears planned to attend the listening party for her husband Kevin Federline’s excuse for a rap album at Pure nightclub in Las Vegas this past Friday.

The pictures have come out from the event, and Britney is nowhere to be found. Is she fed up with K-Fed? We reported on Saturday that she was said to be enraged with Kevin when seven month-old Sean Preston fell off the couch when Kevin was supposed to be watching him. Sources say this may have been the fall that fractured the baby’s skull, not the incident with the highchair.

Britney may have stayed away because Kevin asked her to. The couple was said to be fighting over the fact that Britney gets all the attention at events promoting Kevin. The last time they made a public appearance together was at a belated birthay party for Kevin on March 25th.

Britney is also said to feel threatened by reports that her ex-bodyguards plan to dish the dirt on her, which could include allegations of drug use and details of her sloppy lifestyle.

Here is K-Fed looking like a royal ass at his show on Friday. [via]

Update: Britney may have been pissed that Kevin asked Paris Hilton to come to the party. Paris didn’t attend, and sent her parents instead. Another report has Britney and Kevin arguing in Vegas before the gig, with Britney crying before she went back to their suite.

Instead of fulfilling her dream to model for Karl Lagerfeld, Lohan will have to settle for snapping the fashion designer herself. She’s scheduled to take pictures of Lagerfeld for an upcoming issue of Interview magazine:

Lohan was passed up for a fashion contract by Lagerfeld for being too young, and is said to be desperate to get a high-end fashion endorsement deal. At least she has a sense of humor about it, but it seems rather lame that she’s going to take pictures of Lagerfeld.

Lohan has a lot of projects coming up and will eventually star in a “dark comedy” called Georgia Rule with Jane Fonda and Felicity Huffman. The movie has yet to be written.

Here are Lohan and Lagerfeld at an art opening for Visionaire magazine last night in NY. Also shown are Cher, Michael Stipe and Chloe Sevigny. Sevigny needs to get her eyebrows and hair done.

P. Diddy says that he likes a woman’s nether region fully waxed so he can do his thing. Now that’s normal and a lot of guys agree with him. What’s not normal is the fact that he goes on to say that he likes to wash their hair before he gets busy:

All I can think of is that episode of The X Files where the serial killer washed his victims’ hair and trimmed their nails before killing them. It’s creepy to say that you like to wash women’s hair and it skeeves me out that Diddy is into that.

Here’s Diddy at a listening party for Cheri Dennis’ Album on April 12th. He is shown with Usher, Andre Harrell, Cherri Dennis, Sean Combs and Tracey Weyper.

Tori Spelling’s mom was said to be pissed that Tori was planning on making fun of her eBay obsession on her new faux-reality series for VH1, sonoTORIous. Now that the show has aired, with Loni Anderson playing Tori’s bitchy mom, Tori’s real mom won’t even talk to her.

Tori’s divorce from Charlie Shanian is due to be finalized after a million-dollar wedding and a mere 14 months of marriage. She is now free to marry her fiance, Dean McDermott..

Here she is at the Hollywood Life Reception For “So noTORIous” at Pizarro Design Studio last night.

Paris Hilton is launching a new line of cellphone games, starring herself of course.

Hilton won’t have anything to do with the project except for lending her name and likeness to the game.

Paris held a party at her place Monday Night for her boyfriend Stavros Niarchos’ 21st birthday. (We said it was next week, but we were wrong.) Perez Hilton has the details:

Here are Perez’ pictures. He doesn’t have to make his tag so obtrusive - we know he was there.
