California born and bred, Gwen Stefani has arrived in New York with her family in tow. The pop star has been busy kicking off her Spring 2010 collection for her clothing line, L.A.M.B., as part of Mercedes-Benz Fashion Week.

However, leaving her brood behind on the West Coast was not an option for the No Doubt singer, who is seen here toting her little ones, Zuma and Kingston Rossdale, with her husband, Gavin Rossdale.

Between the fashion events and dining out, the Stefani-Rossdale clan have been staying pretty busy, and stylish at the same time.
