Britney Lives It Up In Las Vegas

It looks like there are two new BFF's on the party scene.

Paris Hilton and Britney Spears partied together in Las Vegas over the weekend, TMZ and People report on their Web sites.

A video on TMZ shows the two ladies dancing to thumping music at a Las Vegas club. The site also has a photo of Spears smoking a cigarette while seated on a couch, supposedly without any pants on. They said the club was so hot that she took off her pants and danced in her fishnets stockings.

People magazine reports that Spears also hung out with rich bachelor George Maloof while in Sin City, checking out the Palms' new recording studio and shopping before heading to the Palms' new club, Moon, where she partied with "Dancing With The Stars" runner-up Mario Lopez.

The magazine's Web site says that Spears won $10,000 playing blackjack.

Spears, 24, filed for divorce from her husband, Kevin Federline, on Nov. 7, citing irreconcilable differences. She is seeking custody of the couple's two children — Sean Preston, 1, and Jayden James, 2 months — with visitation rights for Federline.

The singer's 25th birthday is coming up Dec. 2.
