Gwen Stefani Pictures in London With Zuma and Kingston

Gwen Stefani had her boys Kingston and Zuma on hand this morning for a fun outing to Primrose Hill park in London. The Stefani-Rossdales are abroad visiting with Gavin's family in England following a few fun weeks at home in LA, and today Gwen and Gavin caught up with friends and a young pal. Gwen looked right at home with the small baby — where does she rank on your PopSugar 100 list of your favorite celebrity moms? Gwen put the finishing touches on her No Doubt album with the boys in her band while back on the West Coast, but they spent last Saturday night checking out one of Prince's much-loved shows in Hollywood.
