Gavin and Kingston Rossdale hit the park running yesterday afternoon in Hollywood. The toddler's t-shirt crowned him the playground king, a title he'll likely someday share with his new little brother. You all haven't warmed up to the quirky baby name Zuma just yet, but maybe that will all change when we see the new member of the family. Until we get to meet Zuma and spot mom Gwen out again, we're happy just to see these two Rossdale boys getting back to their summertime outdoors business.
