On Sunday night, Britney Spears took her fans behind the scenes of her life as she prepped the release of her latest studio album, Femme Fatale, in the MTV special "Britney Spears: I Am the Femme Fatale." She allowed cameras to follow her as she hit the studio to work with will.iam, attended dance rehearsals, filmed the video for her song "Hold It Against Me" and performed in Las Vegas.

DJ Pauly D was on hand for that Vegas performance at the Palms Hotel and Casino, where he warmed up the crowd for the femme fatale herself. Before the night even kicked off, Pauly took MTV News for a mini-tour of Rain nightclub, where Spears was set to take the stage for her debut Femme Fatale performance.

He walked our cameras through the club, showing off the stage on which Spears would later perform "Hold It Against Me," "Big Fat Bass" and "Till The World Ends." As he walked across the dance floor, which would be occupied by Spears' fans much later in the night, he made his way to the DJ booth, where he spun tunes and introduced the star the night of the big show, which was included in the special.

"Me, Britney and Vegas is the perfect combination. I love Las Vegas. I love music. Britney Spears loves music. Her new album's out, and who better to be onstage with her than DJ Pauly D?" he said. "It's amazing. I like to see my name on marquees anyway, but now, having it associated with Britney Spears. I've been a fan of her my whole life. I used to always play her music, so it's unreal."
