K-Fed's gonna have to spend some of his babysitting money bailing out the US government -- and it's something he should have done a long time ago.
The IRS has slapped a lien on Federleezy to the tune of $14,371 in back taxes, according to The Detroit News. It's not like he's not making money. Federline is pulling in $30,000 this month alone for babysitting his two kids.
Clearly Kevin's sperm is not only potent -- it's extremely lucrative.
