Britney Spears performs during her mini-concert at the Palms Casino in Las Vegas

Britney Spears performed a three-song mini-concert at Rain nightclub in the Palms Casino & Resort in Las Vegas last night to promote the Tuesday release of her brand new album Femme Fatale. A scantily-clad and sexualized Britney performed three songs from the new album: “Hold It Against Me,” “Big Fat Bass” and “Till the World Ends.”

“Hold It Against Me” and “Till the World Ends” have been officially released but “Big Fat Bass” was new to those unwilling to listen to the unofficially leaked tracks that hit the internet almost two weeks ago.

Britney was sporting an array of sexy burlesque-style stage costumes and performed alongside professional dancers in front of elaborate, colorful set pieces that included industrial caging and over-sized light-up speaker boxes during her performance of “Big Fat Bass.” Here’s a slightly edited video clip of her performance from TMZ:

The mini-concert was reportedly filmed for an upcoming special on MTV and kicked off a Femme Fatale promotional blitz that will include a trip to San Francisco for a Good Morning America special Sunday and an appearance on Jimmy Kimmel Live Tuesday March 29th (the release date for Femme Fatale). There are also rumors circulating that Britney will appear on stage at this year’s Kids’ Choice Awards as well as the Ellen Degeneres Show!

On a side note, Britney’s “opening act” was none other than Jersey Shore‘s DJ Pauly D! I’m guessing MTV was filming his appearance as well as part of his upcoming spin-off reality series.
