Gwen Stefani and Gavin Rossdale’s second son is growing up!
The No Doubt frontwoman shocked her Instagram followers with rare pictures of Zuma on his 15th birthday Monday.
“happy 15th birthday Zuma !!! we love u more than anything,” Stefani, 53, captioned the upload, which featured throwback photos as well as recent snaps.
“I remember when he was first born! Boy how time flies!” one of the singer’s fans commented.
Another sarcastically asked, “How can he be 15 when I am still 23?”
Rossdale, 57, has yet to share his own online tribute to Zuma, whom he and Stefani welcomed in August 2008.
The former couple, who were married from 2002 to 2016, are also the parents of sons Kingston, 17, and Apollo, 9.
The exes’ eldest made headlines earlier this month when he performed for the first time at his stepdad Blake Shelton’s Oklahoma bar, Ole Red.
Kingston sang comfortably in front of the crowd while wearing a Carhartt tee and jeans in videos shared via TikTok.
However, Rossdale told “This Morning” listeners in March 2017 that he didn’t want his four children — including daughter Daisy, 34, from a previous relationship — to follow in his musical footsteps.
“You’ve got to be crazy to have a career in music,” the Bush frontman, 57, explained at the time, adding that he would rather they “go into tech.”

Rossdale clarified, “Whatever they do is fine by me. They’ve just go to be positive, cool people. That’s all I care about. … It is my responsibility to make them contribute to society as opposed to take away from society.”
While he and Stefani have rarely spoken about their co-parenting dynamic over the years, Rossdale did admit in June that they have “opposing views” as “really different” people.
“I think you can go one of two ways,” he said on the “Not So Hollywood” podcast. “You can either do everything together and really co-parent and see how that goes, or you can just parent. And I think we just parent.”
Although Rossdale and Stefani’s styles lack “similarity,” he noted his appreciation of Kingston, Zuma and Apollo being raised with “an incredible perspective” and a “wide view of things.”
