K-Fat K-Dad

Look, it’s professional babysitter Kevin Federline !

The sperm donor was spotted yesterday with his two kids and a bodyguard leaving the Hard Rock Cafe in London.

But nowhere in sight was K-Fed’s gal pal, Victoria Prince.

Reports have it that BritBrit banned her from the tour!

Little Sean Preston and Jayden James look so tired.

We hope K-Fatty isn’t keeping those kids up too late!
