Hot mama Gwen Stefani took sons Kingston and Zuma to the beach in Malibu on Sunday, and the 42-year-old singer opted out of wearing a bikini, but she still gave us a peek at her toned tummy with a cropped top and her fav white maxi skirt.

Hubby Gavin Rossdale is still on tour in Europe, but he'll be back early next week, right around the time Gwen starts going full steam ahead to promote No Doubt's new album Push and Shove. Wonder what the boys will do with dad while Gwen is away?
