You spin me right round baby, right round!

Gwen Stefani and Kingston James McGregor, 3 ½, take a trip on the tire swing during a trip to the park Monday in Beverly Hills, Calif.

The No Doubt frontwoman, 40, and her sons — including Zuma Nesta Rock, 17 months — ran around the playground and even climbed a tree before settling down in the grass to refuel with some orange juice.

Kingston and Zuma are Gwen’s boys with husband Gavin Rossdale.
