A long list of celebrity spectators were at the Friday performance of the opening night of the "Piece of Me" revue which began its two-year residency at Planet Hollywood in Las Vegas, including Miley Cyrus, Katy Perry, Adam Lambert, Selena Gomez, and Mario Lopez--who, according to The Advocate, Spears dragged up on stage for a playful S&M-themed performance of "Freakshow" in which she spanked her former X-Factor co-star with a riding crop as he crawled across the stage.

Though Brit received some criticism for lip-syncing the majority of the songs in her "Piece of Me" revue, the show's "incredible costumes, intriguing set design, and intricate choreography--which the performer seemed to tackle with ease--earned the iconic performer thunderous applause throughout the evening," according to Jase Peeples who was in the audience.

Seven costume changes and a variety of wig switches ensured "Piece of Me" was generously sprinkled with the signature style spectators have come to expect from a Vegas revue while maintaining the persona the pop performer has cultivated over the years. "I'm going to be extremely nervous the first show," Spears told The Advocatea few weeks before "Piece of Me" was to debut. "But I know I'm just going to put my nerves aside and pull it together."
