Gwen Stefani

Is it a rule that, if you have a celeb kid, you can only let them play with other celeb kids?

Coldwater Canyon park was the place to be yesterday afternoon - Gwen and Gavin's young Kingston was hangin' out with the Beckham boys! Check out a shot of K (wearing rolled-up jeans) in a dragon outfit and a shot of Cruz, with their nannies in tow.

Damn, first Sean Preston and Jayden, now David and Vic's kids! Who's next?
