Gwen Stefani's Son Zuma, 15, Makes Stage Debut as He Performs at Stepdad Blake Shelton's Oklahoma Bar

Gwen Stefani and Gavin Rossdale's son is taking after his musician parents.

The 15-year-old made his country music debut on Monday, July 29, after he went up on stage at his stepdad Blake Shelton's Ole Red bar in Tishomingo, Okla. Stefani and Shelton tied the knot in 2021.

Before he walked out on stage, Shelton introduced his stepson, with the two wearing matching cowboy hats as the singer proudly looked on. In a fan video, Zuma can be seen sitting down as Shelton adjusts his microphone and goes, "This is him, everybody!"

In the video, the "God's Country" singer stands to the side as Zuma covers Zach Bryan's song "Oklahoma Smokeshow," sitting on a stool while singing and playing the guitar.

Almost a full year ago, Zuma's brother Kingston, now 18, also performed at Shelton's Ole Red bar in Tishomingo, Oklahoma in a video shared on TikTok.

In the clip, Kingston confidently chatted to the audience and the guitarist who joined him on stage, along with a keyboardist, before he began his performance. During the song — in which he showcased his strong vocal skills — Kingston hit some impressive notes, to the delight of the crowd.

“Love you guys, thank you for being here!” he said at the end of his performance as the audience cheered and clapped. “Thank you, it means everything to me, really. I hope you guys had a great night, enjoy yourselves!”

In April, Shelton opened up about being a stepdad to Stefani's three sons — Zuma, Kingston and Apollo, who she shares with ex Rossdale — in an interview with Entertainment Tonight.

As he chatted about the 10th anniversary of meeting his now-wife, Shelton elaborated on what their future together could look like.

"If I could have a repeat of these past 10 years, [that] would be perfect," he told the outlet. "Next month, we've got an 18-year-old, which it blows my mind that already happened. And in a couple of years, we'll have another 18-year-old. And that's...it's gonna be a lot more alone time, which I'm not mad about that either."

The singer then teased, "But we still have Apollo, so we have another almost 10 years before we can kick him out, so it should be a lot of fun."

Shelton also said that one thing he's loved about being a stepdad is getting to teach Stefani's sons about some of his favorite things.

"I get to teach them the country, you know, and I love that," he said. "Whether it's music, whether it's literally getting out, getting their hands in the dirt or being out on the ranch, seeing the animals, whatever, you know? I absolutely love being the person that gets to introduce them to that stuff."
