While mama Gwen Stefani was busy rehearsing for Jimmy Kimmel Live, sons Kingston and Zuma seemed to be having a grand old time hanging out with dad Gavin Rossdale!

On Sunday the trio were snapped out and about in Santa Monica, and the previous day the family returned back to the states after spending Christmas and New Year's in the U.K. "'Life is moving too fast.where are the brakes? i'm not ready to leave london...." Gavin tweeted the night before they jetted in to Los Angeles International Airport.

Maybe Gwen and Gavin will pull a Posh and Becks and relocate across the pond? Nah, Gwen loves Los Angeles too much to leave...
