Gavin Rossdale held hands with Kingston and led the way for Zuma on their way into the Skirball Cultural Center in LA yesterday. Gwen Stefani and Gavin are all about exposing their boys to the arts, but when it comes to music, they're letting Zuma and Kingston experiment by making noise with pint-sized instruments. The kids were without their generous mom, who donated $1 million to help children affected by the earthquake in Japan. She's also been in the studio working on No Doubt's next album, while Gavin and his band, Bush, have their own record due out this Spring. Gavin bought himself an early present, a new iPhone, to keep in touch with his family and get in extra face time with his loved ones while on the road.
