Gwen Stefani held onto Gavin Rossdale's arm as they walked to their cars in Beverly Hills today. The couple were at Kingston's school for a meeting and chatted in the parking lot before driving away separately. Gwen's been juggling her parenting duties with time in the studio for No Doubt, but she's also made a point to focus on the relief efforts in Japan. The singer announced today that she donated $1 million to help the children affected by the earthquake. She's following in the footsteps of Sandra Bullock, who pledged the same amount just last week. Gwen and her boys recently got away for a few days in Palm Springs, where Gavin also played a tennis match against his pal Roger Federer.
