In case you had any doubts that Britney Spears is back with a vengeance, allow these photos to put them all to rest.

Britney was in full force on Friday night as she kicked off her new tour to support Femme Fatale (which is released Tuesday, March 29). The gig was supposed to be a surprise, but after rumors and reports began to surface, Britney confirmed the news via Twitter and went on to perform like a champ anyway.

The tour kicked off at the Palms in Vegas, and none other than Jersey Shore blowout king DJ Pauly D opened up the night for Miss Spears, who kicked out her old classics, as well as her new smash hit “Hold It Against Me” and the “Big Fat Bass.” Check out a fan video of the latter — complete with Britney dancing her tail off — below:
