Kevin Federline & Britney Spears may fight over custody of children

Rapper Kevin Federline may fight for custody of his children. The shocking claim, comes one day after pop beauty Britney Spears filed a petition for divorce in Los Angeles County Superior Court, citing "irreconcilable differences."

Sources close to Z list star Kevin Federline tell Life & Style Weekly that the soon to be ex-husband of pop queen Britney Spears had no idea she was filing for divorce!

Federline has not had much time to react to Spears' decision to end the marriage, and that' because the soon to be ex-husband of pop queen Britney Spears had no idea she was filing for divorce, Life & Style Weekly reports. Federline was caught offguard when TMZ broke the story Tuesday that Britney filed legal papers in L.A. County Superior Court.

Spears has asked for sole custody of the couple's two small children. Federline is thinking of challenging that, even though Spears has functioned as the primary parent, as Federline tours the country hawking his CD.

Federline almost certainly cannot challenge the prenup. Sources say divorce lawyer Laura Wasser drafted an air-tight prenuptial agreement before the couple married.

Now Foxnews reports, Britney Spears filing on Nov. 6 was no accident.

Spears filed two years and one month from the day of her marriage, on Oct. 6, 2004. Her prenup, according to legal theorists, evidently carried increases for Federline for every year of their marriage. And those deadlines, they say, likely had 30-day grace periods.

Hence, Nov. 6 would have been Britney's last chance to get out of paying a third year of alimony settlement to a basically talentless slacker who was a drain on her finances.

And in the end, money is probably what Spears’ divorce is all about. Since she deliberately showed off a new trim body on David Letterman’s show the other night, Spears is obviously getting ready to go back to work.
