It was a star-studded weekend at Pure nightclub in Las Vegas when Paris and Nicky Hilton, Eva Longoria Parker and Wilmer Valderrama dropped by to kick off the Labor Day holiday weekend on the mega club's VIP stage.

The Hilton sisters were first on the scene -- joined by Nicky's boyfriend David Katzenberg -- to party to the hot tunes spun by Pure's resident DJ, DJ AM. In between dances, Paris and Nicky took a break to pose for photos with fans.

Then Eva and Wilmer dropped in with a gang of friends and joined the party on the VIP stage, where Grey Goose cocktails and shots of Patron Platinum were the drink of choice -- except for Eva who opted for Fiji Water.

The Hollywood celebs were also joined by an A-list of sports figures including Larry Johnson, all pro running back of the Kansas City Chiefs, who was sipping Armand de Brignac Ace of Spades Champagne while he chatted up Lamar Odom of the Los Angeles Lakers, Rudy Gay of the Memphis Grizzlies, the Milwaukee Bucks dynamic duo of Damon Jones and Tyronn Lue and Stephan Bonner of UFC fame.
