Gwen Stefani, Kingston & Zuma Go to Grandma's

Gwen Stefani arrives at her parents’ house on Saturday (April 9) in Hollywood.

The 41-year-old singer and fashion designer and hubby Gavin Rossdale brought along their two boys, Kingston, 4, and Zuma, 2, to see their grandparents.

Earlier this week, Gwen styled the three remaining ladies on American Idol – Pia Toscano, Haley Reinhart, and Lauren Alaina – for the show’s Rock and Roll Hall of Fame songs episode.

Gwen dressed them in her L.A.M.B. collection and accessorized with Noir jewelry.

“The girls were very excited to meet Gwen,” Idol‘s costume designer, Soyon An, told InStyle. “They loved her and thought she was the sweetest.”

FYI: Gwen is wearing Diesel Black Gold Jeans.
