Gwen Stefani had a fun afternoon at Coldwater Canyon Park in LA yesterday with her sons Kingston Rossdale and Zuma Rossdale. Kingston was covered in sunscreen to play with some friends, and Zuma plopped himself on mom Gwen's lap to chow down on some Snapea Crisps. It was a family-filled outing, but Monday included some work for Gwen. She linked up with her No Doubt bandmates for a session in front of the camera. Gwen tweeted, "Had a great photo shoot today [with] Tony Kanal, Tom Dumont, Adrian Young. Can't wait to get into the new songs with you guys." Anticipation for No Doubt's September album helped get fans to vote Gwen into the 2012 PopSugar 100 — find out where she landed on our annual list!
