A dance rehearsal wardrobe malfunction left Britney Spears' right breast exposed on camera on Sunday night (27Jan08). The pop star thought her solo dance routine at dance studio Millennium was a behind-closed-doors affair but website Hollywood.TV managed to obtain a sneak peek through a crack in the window. In the new online exclusive, Spears can clearly be seen working out dance steps for her new video - first in jeans and a white top and then in ripped fishnet stockings and a turquoise leotard. At the end of her pole-dancing routine, the singer takes off the leotard underneath her white T-shirt, but, for a split second, her breast is exposed.
