Of all the celebrity tour demands we've heard thus far, this one take the cake! Despite the fact that Britney Spears is set to launch her "Circus" tour on March 3 in New Orleans, Brit is threatening to pull the plug on her shows unless sons Sean Preston, 3, and Jayden James, 2, can come along for the ride.

Why the fuss? Britney is concerned about who will watch her kids while she is gone.

Britney, her father Jamie Spears, and Kevin Federline had made an amicable agreement that would allow the kids to travel with their mother. In exchange for the privilege, Brit would allegedly pay Kevin $4,000 a week for each week she's on tour.



And although Britney would have homes across the country within commuting distance of her shows, when K-Fed's lawyers heard about the proposal, they flipped -- and refuse to say why. No final agreement has been made, but Britney posted this message on her website earlier today: "Both Sean Preston and Jayden James will, in fact, be joining Britney throughout the duration of her tour." We'll have to wait and see.

But one thing is sure. Britney is finally making an effort to be in her boys' lives, to be a mom.

But Britney isn't like you or me. Sure, lots of mothers travel for work, close to half of all business travelers, according to the Travel Industry Association. But the vast majority cannot and do not bring their kids. In fact, they relish the peace and quiet of time away from the nitty-gritty of domestic life. That is exactly the one thing Britney doesn't have. Maybe, just maybe, she wants to create a home life on the road.

Even if she totes the boys right along with her, backstage and all, how much time could she really have with them? And given the nature of her concerts, would it be more appropriate and less selfish for Brit to leave them home?
