Looks like Kevin Federline is just piling up the job offers. The latest? Making a run for the border – as in Taco Bell. An open letter to the former Mr. Spears was posted on PerezHilton.com, and, in it, Taco Bell's president invites K-Fed to work for the fast food chain "for an hour," and says that anyone who actually shows up to watch Kev scoop beef and fold tortillas will get free food. The exec also references Kev's proclamation last year that his kids would have to work for Taco Bell, regardless of how rich they are. Given their parents' respective paths, that might not be too far from reality.
