Well, work Britney. Ms. Spears has been promoting her new single "Work B*tch" for a bit and finally brings the heat in the accompanying visual. Joined by leather clad dancers, the 31-year-old pop star mirrors the sexy, sandy dance scene we saw in Beyonce's "Baby Boy" video. She's also joined by mannequins and sharks as she flaunts her toned bod in the Ben Mor-directed vid. Watch Britney strut her stuff above.
