Gwen Stefani: Swinging with Zuma!

Gwen Stefani goes for a swing with her 2-year-old son Zuma during a trip to the park with husband Gavin Rossdale and their other son Kingston on Tuesday (August 3) in Malibu, Calif.

The 40-year-old “Sweet Escape” singer started the day off in a gray sweatshirt before warming up and taking it off. Her adorable boys later played in the sandbox together!

Last week, Gwen and Gavin took Zuma on a shopping spree at Trico Field in Beverly Hills.
