So many dresses, so many premieres!

Jessica Alba attended another premiere of Machete last night -- this time at the 67th Venice International Film Festival, but this dress is a marked improvement over the fug floral frock she wore to the photo call earlier in the day. We're thrilled to see that Jess is showing off her bangin' bod, but what's with the train in the back???

And Marc Jacobs pushes her around in a shopping cart! When classy goes trashy. Lady Gaga "graces" the cover of V Magazine - it wouldn't be a photo shoot if Gaga wasn't in her bra and panties - along with fashion king Marc Jacobs for the New York issue. Fierce.

Lady Liberty never looked so good!

And at the Viper Room of all places! Here's a super slim Kelly Osbourne (sporting some longer blonde locks) walking arm-in-arm with Pussycat Dolls founder Robin Antin into the venue Wednesday night...

Kelly also took to Twitter before and after her performance, even posting the below pic of herself in a sexy black bra!

Werk it, girl.

Karissa Shannon is showing off exactly why Playboy came calling years ago ... literally! While working the red carpet at La Vida, wearing a skin tight red dress with cut-outs, the sexy blonde had a wardrobe malfunction.

As for why her dress "accidentally" slipped off her breast, Karissa tells our X17 videographer, "We didn't have time to stop and get boob tape." Wait, is it really a big deal considering the world has already seen her naked in Playboy? Makes you wonder.

After helping his lady get her dress in check, Shannon's boyfriend, actor Sam Jones III, took the opportunity to express why he thinks Spencer Pratt pulled the plug on the alleged sex tape. He tells us, "Spencer shied up."

Spencer ... shy? That's a good one.

We were wondering who that yummy guy was!

The other day Lindsay Lohan went shopping at the Grove in Los Angeles, and she struck a pose with a guy who we have now identified as Dutch hunk Jim Bakkum. Apparently he's like the Justin Timberlake of Holland -- only hotter! Maybe Lindsay can convince him to move to LA?

Kendra Wilkinson is back to her pre-baby fine form ... and looks like she got there with a little help from Svedka Vodka's BartonBotCamp in New York.

Showing off her toned and tight tushy, we're told Hank's wifey is a pro at the Bot Lunge. We can see that her hard work has payed off!

Spies inside the class overheard Kendra asking, "When are we having cocktails ... before or after class?"

That's why we love Kendra.

From the sexy neutral-toned corset dress to the mile high shoes, Kim Kardashian was looking hot hot hot last night! The reality TV starlet and her BFF Jonathan Cheban hit the Viper Room for Robin Antin's Pussycat Dolls Review, and even though Kim dresses the part of the party princess, we know she didn't get into any mischief! After what she told Jay Leno the other day, it seems like she is one of the best behaved celebs in Hollywood!

So what did Kim K. have to say when asked whether frenemy Paris Hilton should go back to jail?

David and Victoria Beckham threw their adorable son Romeo (inset) a birthday party at Ultrazone Laser Tag in Sherman Oaks yesterday, and the middle Beckham child celebrated with famous pals like Heidi Klum's kids! Victoria rocked a sexy green frock, and David kept it casual, as did the boys.

Aww, wonder what little Leni brought for Romeo?
