Britney's hubby Kevin Federline has been slammed in reports recently for not being the doting father he should be. Seems he was spending too much time staying out late and getting his hair braided. Well, the man's been busy preparing to take on the music world, and you can listen to a portion of his song "Y'All Ain't Ready" by clicking here. I guess his hip-hop moniker is K-Fed? Sure, why the hell not? His rap stylings fall somewhere between Vanilla Ice and that time Barney Rubble rapped in a Fruity Pebbles commercial.
