On tour with Britney Spears his Nicki Minaj, and she too took to twitter saying, "Born ready Brit! Time to give the kidz (sic) what they've been waitin for.... Femme Fatale Tour!"

Britney hit the stage with her hit song "Hold It Against Me" and then tore through a 22-song-set that included hits like "Toxic" and "Till The World Ends." It is also reported that Britney graced the stage with some rather racy outfits including a kimono-style gown, fishnet stockings and studded denim hotpants.
The "Femme Fatale" tour will make a stop in New Orleans at the New Orleans Arena on July 15th.
