Gwen Stefani: Sunday with Zuma!

Gwen Stefani holds hands with her son Zuma as they walk through a park on Sunday (October 23) in the Primrose Hill section of London, England.

The 42-year-old singer watched as her little boy kicked around a ball and even helped him swing across the monkey bars!

The day before, Gwen took Zuma and her older son Kingston to a playground where the two had fun on the swings!

FYI: Zuma‘s sweatshirt says “BLAST GATHER TOGETHER”. Gwen is wearing Dita Savoy frames in Dark Blue Swirl. Gwen & Gavin are using their Peg Perego Skate stroller!
