Watch Gwen Stefani, Gavin Rossdale’s son Zuma sing at Blake Shelton’s bar

The teenager stepped out with a guitar in hand, playing the instrument on a stool in a cowboy hat, jeans and boots.

Shelton, 48, sat close by and watched with a smile as Zuma sang Zach Bryan’s “Oklahoma Smokeshow.”

Social media users gushed over his talent after audience members shared glimpses of the surprise solo performance.

“Oh my god he’s so good ???” one person wrote via X, while another praising the teen’s “incredible” vocals.

Zuma’s viral moment comes one year after his older brother, Kingston, similarly wowed fans at Shelton’s bar.

The 18-year-old cut a casual figure in a baggy Carhartt tee and jeans as he sang.

He concluded by thanking the audience, saying, “Love you guys, thank you for being here! Thank you, it means everything to me, really. I hope you guys had a great night. Enjoy yourselves!”

Kingston was born in 2006, followed by Zuma two years later and their now-10-year-old brother, Apollo, in 2014.

Stefani, 54, and Rossdale, 58, called it quits in 2015.

By the time the former couple finalized their divorce in 2016, the No Doubt frontwoman had moved on with Shelton.

She and her fellow “Voice” coach got married in July 2021.

Shelton gushed to Entertainment Tonight in April about getting a “different kind of self-worth” from helping the L.A.M.B. designer raise her boys.

He spoke about his plans to “teach them country,” from music to “being out on [his] ranch” in Oklahoma.

The following month, Rossdale told Us Weekly that Zuma had “the country bug” — but claimed he had “no idea where he got it.”

The Bush frontman joked, “[It] the last thing I want to hear in my house, really, to be honest. … That’s how much I love him. I will support him making any music. Even the blues.”
