Making most of the summer, the 40-year-old singer and husband Gavin Rossdale took their sons Kingston and Zuma out for lunch at Plate in Malibu on Thursday (August 5).
After feasting on an all-organic menu, the happy foursome greeted the paparazzi with a smile before heading home just before dark.
Gwen and Gavin, who married in 2002, have been enjoying a summer off with their children with neither musicians having worked in the past month.
After completing a reunion tour last summer, No Doubt went on hiatus and Gwen put her solo career on hold to focus on her family and fashion lines.
Gavin is due to return to work in the next couple of months with a reunion concert for his band Bush, scheduled for September 25 in Los Angeles, followed by a world tour.
