Britney Spears 'Legitimizes' Pauly D's DJ Career, 'Jersey Shore' Star Says

Shortly after it was announced that Pauly D would be the resident DJ at Rain nightclub at the Palms Hotel and Casino in Las Vegas, the "Jersey Shore" star was bestowed with another honor: He was to DJ Britney Spears' surprise gig in Las Vegas, which was taped for her MTV special "Britney Spears: I Am the Femme Fatale," airing Sunday at 9 p.m. ET.

"For me, I love Las Vegas, I love DJing. It's my heart. I locked down this huge residency, which I always wanted, and now I find out Britney Spears is performing her new album at Rain while I'm DJing. I couldn't ask for anything more," Pauly D dished to MTV News last Friday.

"I'm at Las Vegas now. What it means to DJ a concert like a Britney Spears concert or something like that, it's an association with monsters like Britney Spears and it just legitimizes your career. And it's just fun like being onstage with Britney Spears performing like she's performing. I love it. I couldn't ask for more."

Given that Pauly D plays a mix of popular music and more underground house, he admits that he doesn't have to change his style up too much for a gig with Spears. "I keep up on music. I keep up on current music. I play everything. I'm open format," he explained. "I play geared to the crowd, so I don't prep my set. For this I go out there, I kind of wing it. I look at the crowd, I have an idea. I like to play the new stuff that's hot. I feed off the crowd."

Pauly also explained the rules he has for his craft. "A DJ should not play the artist's songs at her concert 'cause she has to perform these songs," he said. "I'm not going to be playing any Britney before she performs; maybe after. I'll let her perform, let her shine 'cause it's her night."

The Vegas show is one of many highlights in the "I Am the Femme Fatale" special. Spears gives fans a taste of what it was like making the album, including behind-the-scenes footage of her in the studio with will.i.am and an intimate chat with Sway Calloway in which she opens up about her life and her career.

To see what Spears has to say about her new album and watch her as she puts the finishing touches on it, don't miss the "Britney Spears: I Am the Femme Fatale" special, airing Sunday, April 3, at 9 p.m. ET on MTV.
