Baby Zuma Rossdale enjoyed a fun-filled Sunday morning (September 20) at a Beverly Hills park with rocker dad Gavin Rossdale and his fashionable mom Gwen Stefani.

While Gavin stayed cool in cut-off denim shorts and a basic white tee, his No Doubt frontwoman wife glowed affectionately in the pressence of her newborn son despite the fact that she was sans makeup.

Gwen — who just wrapped up a summer tour with No Doubt — is currently hard at work in the studio working on the band’s highly-anticipated upcoming album. Gavin, meanwhile, has two more dates on his mini solo summer tour.
