K-Fed Dishes About His Buns

Is the world ready for a clean cut K-Fed?

Federline spoke to "EXTRA" while on the set of his new Super Bowl commercial where he revealed his shocking wardrobe for 2007 -- "You won't see me outside of a suit unless I'm going to the grocery store or something on Sunday!" Federline without his t-shirts and trucker hats?

The FedEx kept quiet about his split from Brit, saying only, "I always try to stay positive, no matter what."

His commercial has him working at a fast food restaurant after day-dreaming about his success as a rapper. Dream on.
