The Stefani-Rossdale's Gloomy LA Day

Rocker parents Gavin Rossdale and Gwen Stefani braved some dreary weather on Sunday (January 2) as they made their way to a friend’s birthday party in LA with their handsome sons, 4-year-old Kingston and 2-year-old Zuma.

Gavin made a couple pre-party stops, including a trip to Starbucks and Walgreens, while Gwen was looking a little less impressed to be out in the rain. Kingston and Zuma were as cute as ever in their super stylish get-ups.

The last time we spotted the Stefani-Rossdale brood was on Christmas Eve, where the boys were treated to a visit with Santa at the Westfield Mall in Sherman Oaks, Calif.
