Federline dreams of family roadtrip

Britney Spears' husband Kevin Federline has a dream - to take his family on a bus tour across America.

The wannabe hip-hop star hopes his music career takes off so he can treat his wife and kids to a cross-country road-trip.

Federline, who currently has a baby son and another child on the way, says, "I'm going to try to do the bus thing, and bring everyone along."

And Federline hopes the planned bus tour will be the romantic trip his wife craves.

He adds, "I feel bad. It's been a while since I've been able to take her away."
