Britney Spears Dances Through her Monday

Preparing to put on a series of spectacular Vegas shows, Britney Spears rehearsed at a dance studio in Thousand Oaks, California on Monday (May 20).

The “Scream & Shout” singer was dressed for a serious sweat session in a gray tank top, gray sweatpants, and no makeup.

Last week, the 31-year-old songstress” new tune off of the “Smurfs 2” soundtrack made its way onto the net.

Unfortunately, the leak was a bit premature, as the pop princess later clarified, “I heard an early demo of #OohLaLa smurfed its way onto the internet today 🙁 The real version will be at radio and iTunes June 16th :).”
