Pictures of Gwen Stefani, Gavin, Zuma, and Kingston Rossdale at a Party

Gwen Stefani had her hands full Friday afternoon bringing Zuma and Kingston to a superhero birthday party in LA. The threesome were greeted by life-sized Star Wars characters for the fun, playful afternoon of exploring the bouncy house and testing out the inflatable slide. Zuma and Kingston both dressed as Batman, and the little brother made lots of his usual funny expressions before taking off his costume and getting his face painted. Kingston's celebrating his fourth birthday later this month but he's still a momma's boy, snuggling up in Gwen's lap toward the end of the party.

The weekend fun didn't stop there, as yesterday Gavin and the boys snuck out of the house on an early morning shopping trip to pick up balloons, food, wine, and flowers for Gwen on Mother's Day! Gwen and Gavin are back in LA with the boys after joining other sexy couples at the Costume Institute Gala last week. Gwen was a knockout in her ivory and black L.A.M.B. dress while Gavin kept his look classic in a black tuxedo.
