Britney Spears is begging her ex-husband, Kevin Federline, to have a vasectomy because she doesn’t want the father of four having children with any other women. “She doesn’t want the money she gives Kevin to help support a child he might have with Nicole or anyone else,” a tabloid snitch dished.

A National Enquirer insider reveals:

“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.”

“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.”
