LAS VEGAS-Britney Spears, in the heels of such performers as Celine Dion and Elton John, late Friday opened a two-year sojourn in Sin City with a dazzling performance to a crowd of adoring fans.

The former enfant terrible of US pop wowed some 4,600 fans with a stunning show at the Axis Theater at the city’s Planet Hollywood Resort and Casino. The Grammy-winning pop songstress was hired to perform her new spectacle, titled “Piece of Me,” 50 times a year in 2014 and 2015. “Wow perfect audience for the 1st Piece of Me show. That was amazing. The 32 year-old Spears wrote on Twitter. In the 90-minute extravaganza, Spears lip-synched more than 20 songs, including many of the hits she had over her 15-year career from former Disney starlet in the late 1990s to pop diva of the 2000s. Against a backdrop of stunning video projections, Spears performed such hits as “Toxic,” “Womanizer,” “Baby One More Time,” “Scream and Shout,” and “Till the World Ends.” Spears, who has sold some 100 million albums so far in her career, had help from a troupe of dancers that writhed, wiggled and did back flips at a steady pace throughout the show. After being delivered on stage inside a metal sphere, Spears showed up in a large winged angel costume to sing “Everything,” while she sang “Toxic” perched on a giant stage tree.
