Britney Is Back! Her Las Vegas Show Looks Pretty Amazing

Oh My Goodness. Britney is back!

The singer took to the stage in Planet Hollywood in Las Vegas last night for the first of her two-year residency *screams with excitement*.

Glitzy bodysuits, massive angel wings, glow in the dark outfits and some pretty sexy dance routines - the Piece of Me show had it all!

Rumour has it the show included seven costume changes and two wig changes as Britney sung 23 (yes, 23!!) songs. Wowsers! Britney knows how to work it!

Picture the scene - you're in the crowd buzzing with excitement, then suddenly Work Bitch is being pumped out on the speakers and then... BRITNEY APPEARS!

Plus, all of that is followed by some pretty amazing classics - Toxic, Boys, Opps... I did It Again - you get the idea!

The show even saw Mario Lopez jump on stage and get down on all fours as he was walked on a lead. Dominatrix Britney!

The likes of Selena Gomez, Katy Perry and Miley Cyrus were among the celebs in the crowd. Check out there dancing and all of the rest of the pics from the show here...
