Gwen Stefani barely got back to California a few days ago, but she showed no time needed for relaxation. We caught these fotos of Gwen as she took baby Zuma shopping at Barney’s of New York. Gwen wore a black jacket and white top, sticking with her well-known palette. Zuma wore a red sweater and stripped white/green pants as mother and son shopped along happily in Beverly Hills, California. Look how old Zuma is, already sitting up on his own.
