Gwen Stefani & Gavin Rossdale Hit The Grove

Gwen Stefani arrives at The Grove with sons Kingston, 3, and Zuma, 1, to support her husband Gavin Rossdale as he performs at The Grove Summer Concert Series in Los Angeles on Wednesday (August 26).

Last week, the 39-year-old singer threw an outdoor party for Zuma‘s first birthday. Gavin helped out by preparing food early in the morning.

“I got home from the studio and was cooking burgers at 3 a.m. this morning to prepare for the party,” Gavin told E!. “I’m the chef, and Gwen‘s more of the party planner. She takes care of the presents and the guests. I just love to cook for everyone.”
