'Shore's' Pauly D reveals his product-free Bieber 'do

When Paul DelVecchio, better known as DJ Pauly D, showed off his post-shower, pre-product hair in an unaired clip from MTV's "Jersey Shore," he shocked his pals.

Seems without the disc-spinner's usual plastered back blow out, castmates Sammi Giancola and Angelina Pivarnick barely recognized him. Maybe that's because an uncharacteristically limp locked Pauly D, by his own admission, looked more like "Justin Bieber, yo."

NSFW warning: Dial the volume down if Pauly D's potty mouth is a problem.
