Britney's back in shape and reading to tour her Circus around America, but can she stay out of trouble and stick it out?

Britney flew back to Louisiana with sons Jayden James and Sean Preston to chill with her family before kicking off her tour tomorrow night in New Orleans.

Brit's tour is set to be her most racy one yet and she promises loads of singing, dancing and some serious magic tricks.  If she could make Justin Timberlake appear out of her top hat, then we'd be well impressed!

Britney's had a difficult come-back - she's had to deal with criticism over lip-synching and being too curvy, but now she's back on form and ready to wow!

But with a whole new generation of our fave girly singer like Katy Perry and Lady Gaga, can Britney still keep up and regain her Princess of Pop title?  We'll just have to wait and see!

Watch her video for Circus to get you in the Britney mood...

Are you going to see Britney's Circus when she plays here London and Manchester this summer!
