Gwen Stefani and Gavin Rossdale kicked off their weekend in LA with Saturday's star-studded art party before enjoying a low-key afternoon with their boys yesterday. Kingston was in his yellow t-shirt for some playtime with his parents, while Zuma showed off his latest fashionable bib. The Rossdale kids have been enjoying the great outdoors recently, between their trips to the park and their Halloween fun. Gwen, meanwhile, is focusing on growing her fragrance empire as she just announced that she's adding five new scents to her Harajuku Lovers line.
