The Stefani-Rossdale family had a busy few days in LA, starting with Gwen taking Kingston and Zuma to visit their grandparents in Hollywood on Saturday. Yesterday, though, was all about a trip to the zoo. Gavin joined them for the adventure, which began with Kingston and Zuma getting a security escort into the park. Gwen and Gavin followed behind with their strollers, and, once inside, they all checked out the exhibits and played on the animal statues. Gwen's been all about spending time with her boys when she's not in the studio with No Doubt, but she recently took a break from both to pose for Elle's Women in Music Issue.
