How utterly priceless are these fotos of Gwen Stefani? The No Doubt rocker took her children Kingston and Zuma to a play park yesterday. Gwen put Zuma on the swings while Kingston played in a sandbox. Gwen wore a black jacket with the words Harajuku Lovers written on the back, which is Gwen’s more accessible label, over the haute L.A.M.B. Gwen also wore blue jeans and black Ugg boots. Zuma wore a black sweater with the words I Love My Life written on the sleeve of the shirt. How appropriate!
