Gwen Stefani hopped out of her car and headed into a studio in Santa Monica yesterday. She got back to work on her latest album with No Doubt after sharing a fun afternoon with her family on Tuesday. Gwen, Kingston, and Zuma went to the Irvine Railroad Park, where they got a head start on celebrating Easter with an egg hunt and a photo op with the Easter Bunny. Kingston and Zuma also rode a train, played in the grass, and climbed trees with the help of their grandpa Dennis. Gavin Rossdale didn't make the trip since he was on set filming The Bling Ring in LA. Gavin has since wrapped work on his small part in the Sofia Coppola film and shared on Facebook that he's "ready to get back to my Bush day job."
