Britney Spears' Boys: Christmas Carol With K-Fed

Kevin Federline and his girlfriend Victoria Prince take his sons Kaleb, 5, Sean, 4, Jayden, 3, and daughter Kori, 7, to watch the new animated flick, A Christmas Carol, on Sunday (November 8) at the Pacific Theaters in Chatsworth, Calif.

The 31-year-old dad is watching Jayden and Sean while mommy Britney Spears is on tour in Australia.

Kevin is also looking a lot slimmer compared to a few months ago. Looks like his involvement with VH1′s Celebrity Fit Club is paying off!
