From racing around town in his sexy whip to shaking his body at the dance studio, Justin Bieber had quite the busy Friday!

The 21-year-old pop superstar hit the studio in the late morning, and he later posted a video of his rehearsal. Not only is he shirtless, but we're quite impressed with the way he moves his hot bod!

Bieber may have received some criticism for his recent Men's Health cover (not from us though!), and last month he took to Instagram to silence the haters who were claiming that the pictures were enhanced. "I love the fact that I got in shape the past two years and I’m finally getting the recognition for it," Bieber said at the time. "It's not Photoshopped for all you fools out there saying it’s Photoshopped."

Hey, we believe him -- and we can't get enough of the pics and videos he posts! Check out his dance moves below:
