The party doesn't stop for Gwen and the gang!

Yesterday, the 42-year-old singer and her sons Kingston and Zuma were spotted on their way to a birthday bash in Long Beach and looked adorable as they all held hands en route. How cute!

The No Doubt frontwoman was probably enjoying her downtime as she and her band are almost done completing their new album. “Last of the studio days I love this record gx,” Gwen tweeted along with a close-up of her in the studio. The new record is expected to hit stores September 25. Can't wait!
