Gwen Stefani Zuma Rossdale white Studio City

Can you believe Gwen Stefani is a 43-year-old mother of two!? She just keeps getting better with age...

Yesterday the singer dropped her youngest son off at summer school, and we're not sure if she had plans to go anywhere after this, but she looked absolutely amazing in a simple white tank and animal print skinnies.

Over the weekend mama Gwen took her two boys to Knott's Berry Farm in Buena Park with her parents Dennis and Patti, but by the end of the summer it looks like she's going to be back to the grind, as No Doubt is reportedly set to hit the road again after postponing their tour earlier this year.

Back in February the band confirmed via Facebook that they were working on their seventh studio album, and they added, “We have decided to follow our muse for the time being and focus on this new music that we don't want to stop. So, we will be postponing our tour plans briefly while we endeavor to create something special and inspired. Our goal as a band is to share this new music with you as quickly as possible -- both recorded and live on tour.”

Still no word on when the tour will resume...
