Britney Spears rolled into New Orleans where she will kick off her comeback tour on March 3.

The Piece Of Me star arrived in the city on her tour bus, accompanied by sons Sean Preston and Jayden James, her father Jamie, bodyguards and her full tour entourage.

Looking ready to live out of bags for the next four months, a make-up free Britney already looked worn out as she hid behind big umbrellas.

Ex-husband Kevin Federline has negotiated a deal with Britney to allow the boys to join her on tour.

The wannabe rapper will also be joining his ex-wife on the tour and is being paid $5,000 a week to accompany his kids.

The Daily Mail reports Britney will have three bases - in New Orleans, New Jersey and Los Angeles - where the boys will live while she travels to nearby venues.

Kevin will also have his own apartment at each base.

Kevin's lawyer Mark Vincent Kaplan said: "They will be available in her life when she is done with the rigours of performing."

"He is doing that because he wants her to be able to have the maximum positive environment around her to assure that the tour will be successful."
