Kevin Federline Calabasas gas tattoo Someone still hasn't lost the baby weight!

Kevin Federline stopped to fill up his gas guzzling car in Calabasas, and the father of five looks like he's been eating one too many chicken McNuggets off his kid's plates! The former backup dancer hid his figure in baggy shorts and a red t-shirt.

His ex-wife Britney Spears, on the other hand, has never looked more fit! The pop star has been amping up the glam for her new gig as an X-Factor judge, and if anyone has any doubts she's perfect for the job, just ask Simon Cowell!

We wonder if K-Fed will bring Sean Preston and Jayden to sit in the audience?!
