Watch Pauly D Dress As Justin Bieber In A Commerical For Never Say Never

We can say with no shame we have not one clue as to how this all happened. Did MTV approach Bieber's people? Did Pauly D's new manager Larry Rudolph promise Biebs a duet with Britney if Pauly D could share a screen with him? We're talking about the below video, in which "DJ" Pauly D dresses as Justin Bieber to promote the singer's new movie, Never Say Never. The D rocks a total Bieber look—hoodie, purple skinny jeans, high tops, and of course, the requisite bangs. We're not sure about the pearls (WTF?) on JB, or the fist-pumping, or really anything...what's next, Bieber as a gorilla juicehead?
