Now this is the Britney Spears we know, love and remember! The pop diva cracks the whip -- literally -- in her video for 'Work Bitch.'

Wearing a variety of belly-baring outfits -- we counted at least five but got distracted by Brit's body -- the diva dances on a white plank in the desert, surrounded by dancers. They do a dance that looks like they are riding imaginary bikes. She also dances by a body of water, against a white backdrop and in a club. Bikinis and heels are her uniform, and she flogs a lady wearing a similar uniform, playfully.

There are scenes of erotic dancing, adult clubs and more. All the bacchanalia of Las Vegas (her new home) is well-representated here.

It's the antithesis of her 'Ooh La La' video, which featured her two sons.

Britney's back, b---h. Does that body hurt you, Brit? It's KILLING us!
