The pop princess reclaimed her crown as cheering fans screamed for more from the mother of two.

The big shock came when the notorious lip syncher actually sang one song live during her set. We all know that Britney like Madonna is more of an entertainer than a singer. Click here to see more pics from the show.

BRITNEY SPEARS shocked everyone as she kicked off her first world tour in five years – by actually singing a song.

There’s bound to be plenty of controversy over this spectacular and very naughty show, but it’s the fact she used her voice, as well as the rest of her body, that left us open-mouthed.

Mind you, it was only one song.

The fallen pop princess rose from the wilderness at the New Orleans Arena with one of the rudest performances ever seen.

She was tipped to mime throughout the entire Circus live show, as she did on X Factor.

But Bizarre were there with ears pricked and, at the end of the second act — bingo! Britney sang drippy ballad Everytime with her pre-recorded vocal track reduced to a minimum.

Under normal circumstances you might think one live song for £100 a bit steep, but Britney is not a normal pop star.

And it is amazing to see her return with such an incredible show when, not long ago, we all wondered if she would ever step foot on a stage again.

And to be fair, it would have been pretty hard to have enough puff to sing for 90 minutes as she sped through a mind-boggling 15 costumes — including some of the raunchiest ever seen in a pop show.

She went from PVC vamp, to nipple-tassled sex bomb, dazzled in a gold body suit and all manner of other curve-hugging creations.

KYLIE MINOGUE’s right hand man WILLIAM BAKER designed the outfits — and he didn’t hold back.

Meanwhile, knife-wielding martial artists, aerial acrobats, clowns, and scores of dancers jostled for space with her on the stage.

The mum-of-two has never been naughtier and she startled the 17,000 crowd with her risqué antics.

A kinky bondage theme featured heavily.

Male dancers sported S&M-style leather masks and a video segment saw the star in what can only be described as a sex dungeon.

Britney’s bound to face criticism for the filthy nature of the tour — which comes to the UK in June.

This is no family show. source
