K. Fed's Baby$itting Gig

Kevin Federline is following ex-wife Britney Spears on tour to take care of sons Sean Preston Tater Tot and Jayden James Small Fry.

His rate for babysitting?

During the month of June, K. Fed will rake in $30,000 on top of the $20,000 he already gets for child support.

Plus, Kevin is taking his girlfriend, Victoria Prince, on the trip!!!

We heard she was banned from the tour!

Maybe she is on the payroll, too.

This could get interesting!!!
