She's got a hit album that just went platinum, is about to release her [article id="1603367"]third single[/article] and has a sold-out tour in the works. But, according to TMZ, [artist id="501686"]Britney Spears[/artist] has threatened to cancel her upcoming [article id="1603689"]Circus tour[/article] if ex-husband [artist id="2099561"]Kevin Federline's[/artist] lawyers insist on blocking an agreement that would allow her to take the couple's two sons on the road with her.
Citing unnamed "informed sources," TMZ reported that for several weeks, Britney, her father, Jamie Spears, and K-Fed have been privately working on a plan to let Sean Preston and Jayden James travel with the singer while she goes on the 33-date tour.
According to the plan, Britney would have three home bases while on tour — in New Jersey, New Orleans and Los Angeles. The boys would stay in one of these three bases, and Spears would commute back and forth to them while doing concerts in each region. The tour is slated to kick off in New Orleans on March 3.
A spokesperson for Spears and tour promoter AEG Live could not be reached for comment at press time.
TMZ also reported that Britney would pay K-Fed more than $4,000 a week for each week she's on tour, and her ex would have his own apartment in each of the three home cities. The reason the plan has allegedly hit a hitch is that they worked out the arrangement without the help of lawyers, and Federline's lawyers were "furious" when they heard of it. The attorneys reportedly felt that Jamie Spears, the conservator of Britney's estate, went behind their backs to the cut the deal.
Unnamed sources told TMZ that Federline's lawyers object to the plan, but have not specifically stated why. According to the site, Spears has a nearly 50/50 custody agreement with Federline, but this tour flap could also put that current arrangement in jeopardy.
