Gwen Stefani wore her latest updo and toted her current favorite L.A.M.B. bag to join Gavin Rossdale for lunch at The Ivy in LA yesterday. The couple have been enjoying most of their Fall close to home, hanging out with Kingston and Zuma and setting aside some alone time together. They spent a low-key afternoon in a park with their boys last Saturday before getting glammed up to attend the MOCA gala. This weekend has another big event in store, as Gavin's slated to perform at the American Music Awards with Carlos Santana on Sunday.
