The No Doubt frontwoman, 43, was her usual fashionable self in a pilgrim-inspired white shirt, black blazer (with pronounced shoulder pads), houndstooth shorts, black tights and booties as she held her adorable pooch; alongside her, Bush singer Gavin, 47, stayed true to his rocker roots with an unbuttoned white shirt, black vest, chunky belt, black zippered pants and boots. The day's natty scene stealers -- as usual! -- were little Kingston and Zuma.
The blonde brothers wore matching seersucker jackets and bow ties, with older brother Kingston donned seersucker shorts with a dog pattern plus motorcycle boots; Zuma complimented his blazer with jeans and white Converse sneakers.
Reuniting with No Doubt earlier this year for a new album, Stefani has admitted that her life has changed drastically since becoming a married mom.
"I told [my bandmates], 'I cannot do twelve-hour days anymore, stop it!' " she told Vulture. "I just missed Kingston and Zuma going to sleep. But I get to talk to you, and it's actually a nice break — my kids are so much work," she said, laughing. "No Spider-Man for me tonight, but that's okay. I'll take a break."
