Back in October we saw a few funny photos of mama Gwen Stefani giving her eldest son Kingston James McGregor a stern talking-to on the streets of London, England. This time around, we get to see new photos of Gwen with both of her sons, including Zuma Nesta Rock, under much happier, less uncomfortable circumstances. Gwen and the boys attended a birthday party with friends where the activities included bike riding and scootering. As you can see below, it looks like both Kingston and Zuma had a blast!

It’s inSANE to me how big these boys are. It seems like just yesterday that Gwen was a first-time mom … then she became a mom for the second time … now she’s the mom of bona fide KIDS! I’m not sure if she and hubby Gavin Rossdale plan on having more children but … I could see Gwen going for baby #3 … maybe a girl next time? HMMM.
