Happy Anniversary, Gwen Stefani!

Gwen Stefani and rocker husband Gavin Rossdale hold hands while celebrating their sixth wedding anniversary together at Osteria Mozza Italian restaurant in Los Angeles on Sunday.

Gwen proudly wore her love for her sons, Kingston, 2, and Zuma, 3 weeks, around her neck. The 38-year-old No Doubt frontwoman wore a Jennifer Meyer necklace with two pendants, each with the first letter of her sons’ first names, Z and K. (Nicole Richie also supports Tobey Maguire‘s jewelry designer wife, wearing an “H” pendant/necklace for her daughter Harlow.)

HAPPY ANNIVERSARY, GWEN & GAVIN!
