Some of fashion's biggest designers had their latest runway choices make a splash at the "Teen Choice Awards" this weekend on young Hollywood's biggest stars. Among them were Louis Vuitton, Christian Dior, and Marc Jacobs.

Leighton Meester picked up an award for her role on "Gossip Girl" and is picking up votes for Best Dressed of the night with her black and white striped Louis Vuitton dress. She paired the chic mini, from his Resort 2010 collection, with a pair of bright red Brian Atwood heels.

Britney was the recipient of the "Ultimate Choice" Award at the 2009 Teen Choice Awards at the Gibson Amphitheatre on Sunday. The award is given to celebrate career-spanning achievements.

The ultimate surfboard was preceded by a career montage of Spears, who first hit the "Teen Choice Awards" stage in 1999. "Wow, this is such an honor. Thank you guys so much," Britney said upon receiving her surfboard. "I'm so happy to be here tonight with all of you. From the bottom of my heart, thank you so much and God bless."

Britney Spears is set to perform at the 2009 Teen Choice Awards. The "Womanizer" singer - who is nominated in three categories - will appear on stage at the annual event on Sunday night at Universal City's Gibson Amphitheatre, in California.

Her performance will mark 10 years since the first Teen Choice Awards in 1999, where Britney - who is currently on a break from her world tour - was one of the performers.

The Pussycat Dolls are not breaking up. In fact, despite the rumors which hit blogs and entertainment news agencies everywhere, the "When I Grow Up" singers are working on a new album.

The group's creator Robin Antin took to her Twitter to shoot down the latest rumors on the popular girl group. "The Pussycat Dolls r NOT breaking up.... & IF they ever were, u would hear it from ME 1st, NOT GOSSIP," Antin wrote on the social network. "Album #3 on the way!"

Kevin Federline is headed to Las Vegas, but not just to gamble and party. The ex-hubby of pop princess Britney Spears will be filming a new VH1 show.

The very noticeably heavier K-Fed arrived at the Hard Rock Hotel & Casino in Las Vegas yesterday. He spent the day relaxing at the HRH Beach Pool Club.
