Life & Style claims that K-Fed wanted to surprise Britney with a divorce first, and was trying to use their first child, Sean Preston, as leverage. Kevin met with a divorce attorney in May and wanted work out a hefty $10 million settlement for himself. Once little Jayden James was born, Kevin wanted to up that amount to an unbelievable $30 million. The bastard tried to use their two children as pawns so that he could get more cars and jewelry to “rap” about:

As early as last May, Kevin, 28, began secretly meeting with his lawyer, Mark Kaplan, to work out a settlement deal with Britney, 24. Kevin was prepared to use their son, Sean Preston, now 1, as leverage: If Britney didn’t give Kevin $10 million, plus their $10 million Malibu mansion, he would sue her for custody, claims an insider. “Kevin knows that Sean is Britney’s Achilles’ heel,” an insider says.

But the couple stayed together through the birth of their second son, Jayden James, now 2 months. Yet Life & Style knows that Kevin recently went back to his lawyer for more secret divorce talks — and this time, he had two babies to use as pawns. He was hoping to score a $30 million payday.

“He feels like $10 million is not a generous amount if he and Britney split since he won’t have any part of his sons’ lives,” says an insider.

But Britney was too quick for him. While Kevin was caught up with his troubled album-release tour, she filed papers of her own asking for legal and physical custody of Sean and Jayden — before the couple reached any kind of deal.

“There was no way she was going to let Kevin lead the way on this subject,” says a close friend of Kevin’s. “She filed first to save face. It’s all about taking care of the babies and keeping the money.”

And Brit’s prenup should be airtight. According to the prenup, Kevin will receive $300,000, any gifts Britney bought him that cost less than $10,000 and half the value of their $10 million Malibu mansion.

Perhaps if Kevin had paid more attention to his wife instead of his career and friends, he would have seen the legal war coming. After a bitter fight on Oct. 11, Britney told him, “If you want to act like you’re a bachelor who doesn’t have a family or a wife, I can make that a reality,” says a friend who witnessed the fight. Brit later got on the phone with her mother and told her, “This isn’t working.”

By filing for divorce first and not succumbing to Kevin’s ridiculous settlement demands, Britney is making sure that the terms of their prenup are adhered to:

According to an Us Magazine article from December 2005, here are some of the details of their pre-nup:

• K-Fed won’t touch a penny of Britney’s money. All the millions belonging to Britney will stay that way.
• The mansion will be divided 50/50.
• Any gift given worth over $10,000 will go back to the original purchaser. This includes a custom-built motorcycle Brit gave K-Fed for Christmas 2 years ago.
• She will still support him for a little while longer. Brit will pay Kevin $30,000 a month for the period of time that is half the length of their marriage. Meaning he’ll be taken care of until at least a year from now.
• Spears won’t pay child support. Federline is still responsible for supporting his other two children with previous baby momma Shar Jackson.

This is the woman who once gave K-Fed her no-limit Amex black card to show him that she trusted him, so she deserves a lot of credit for filing for divorce first.

K-Fed has a custom Ferrari worth more than a quarter of a million dollars, a Maserati worth at least six figures, and a $30,000 watch. All that shit is going to go back to Britney!

(Prime Celebrity Tips Network e-mailed me the pre-nup details, and you think they would include a link back to their site, which I could not find.)
