DJ Pauly of MTV’s runaway hit Jersey Shore hosted a Halloween evening at Moon Nightclub inside The Palms Hotel & Casino in Vegas this past weekend. The Jersey Shore’s resident nice guy must be getting more comfortable in front of the cameras because he showed up with his natural hairdo instead of his usual slicked up high volume blow out with more hair gel than Vidal Sassoon ever saw. Of course, he said he dressed up as Justin Bieber, right. Rumors are also circulating that the reality star who is more famous for being on TV than his DJ gigs, is getting his own reality show focusing on his “career.”
