Hello, you either have JavaScript turned off or an old version of Adobe's Flash Player. Get the latest Flash player. Britney Spears gave her fans a big surprise this weekend. The pop princess made an unscheduled appearance.

At the closing event of the White Party, Jeffrey Sanker's annual weekend-long gay festival in Palm Springs, Calif. I'm told she was there because she and one of yesterday's performers, Agnes, share the same manager, Larry Rudolph.

Spears was treated like royalty…I'm told she held court over the party from a $20,000 viewing platform that was built just for her. She was protected by.

At least a dozen security guys who did their best to shoo away any overzealous fans trying to snap pics (sorry, Brit, but photos hit the web as soon as you hit the party). "At the White Party in Palm Springs," Spears tweeted. "Sooooo fun!!! About to check out Agnes."

No word on what Spears thought of another performer on the bill—Real Housewives of Atlanta star Kim Zolciak. The reality star "sang" her dance single, "Tardy for the Party," in what appeared to be a black skirt and bustier inspired by 1980s Madonna. She was joined onstage by her collaborator and fellow Housewife Kandi Burruss and a gaggle of hot, muscled go-go boys.
