Britney Spears -- Back in Black

Leaving the kids and her cowboy hat at home, Britney Spears went back to a North Hollywood dance studio yesterday rocking her sexy black micro-skirt -- much classier than her usual pink and red workout disasters.


After the session, a black Mercedes carrying the Britster emerged from the parking lot -- followed by ten speeding cars full of paparazzi which peeled off into the street after her.

When Britney's on the move -- it takes a village.
