Gwen Stefani and Gavin Rossdale made a Starbucks stop in Studio City, CA, yesterday. They bundled up in black jackets and stuck close together as they clutched their coffee cups. Gwen, who celebrated her 43rd birthday earlier this month, is back on the West Coast after a stint in London promoting her latest album, Push and Shove, with No Doubt. The band is currently rehearsing for an upcoming performance at the MTV EMAs in Germany, followed by a series of shows at LA's Gibson Amphitheatre. Gavin has also been flexing his musical muscles. He's been on tour with his band Bush for the past 12 months, and recently performed a sold-out show at the BayFest Music Festival in Mobile, AL.
