Kevin has two children with Britney and two more with his ex, Shar Jackson. An insider tells the National Enquirer, "After all that's happened, Britney still wants to get back with Kevin-and she certainly doesn't want him having any more children with anyone else. Britney even offered to pay for the vasectomy and promised to get her tubes tied if Kevin agreed to it: She told him: 'You have four. You don't need any more. Please think about it."

Of course, Spears may have an ulterior motive to her plan. The snitch said, "She doesn't want the money she gives Kevin to help support a child he might have with Nicole or anyone else."

Anyone who hopes to be Federline's future baby mama need not worry. According to the source, "Kevin won't get a vasectomy but thinks it's a great idea for Britney to get her tubes tied. He told her: 'Hell no! No one is snipping me! He wants more Federlines."
