They might be superstars, but Gwen Stefani and hubby Gavin Rossdale spent their Sunday afternoon like any American family -- at the farm!

GwenZumaArms230.jpgThe couple took their sons Kingston and Zuma to Underwood Family Farms, where Kingston and Zuma rode ponies and enjoyed popsicles. Too cute!

The boys also played on the playground, with Zuma enjoying a classic kid activity: digging a hole in the sand. Even celebrity kids are easily amused!

And Kingston shared his bag of treats with mom and dad while they got in some couple time on a park bench.

Gwen and Gavin looked like a normal, loving couple as they watched their sons. Check out the super-cute pic of them together after the jump, and watch our exclusive video below to see the whole family together!
