Watch Gwen Stefani's son Zuma make his musical debut at Blake Shelton's Oklahoma bar

For the second time in less than a year, patrons at Blake Shelton's Ole Red Tishomingo witnessed the concert debut of one of his teenage stepsons.

Zuma Rossdale , 15 — the middle of three sons Shelton's wife, pop icon Gwen Stefani, shares with her ex-husband, rocker Gavin Rossdale — played his first public performance Monday, July 29, at Ole Red Tishomingo .

Zuma, who will turn 16 on Aug. 21, covered two songs by up-and-coming Oklahoma country music superstar Zach Bryan during the short acoustic set at his stepfather's hometown restaurant, bar and venue.

"I had no idea that he was going to come out ... and sing until Blake started talking," said concertgoer Jamie McGaugh, a devoted Shelton fan from Coalgate.

"He did mention Kingston , and he said Kingston's influence was Gwen, but Zuma's influence was him — and he was all proud about that."

An Ada native, Shelton, 48, made Tishomingo his adopted hometown several years ago, and he opened the first location in his Ole Red bar and restaurant chain there in 2017. The eight-time Grammy nominee is known to occasionally perform at his Johnston County hot spot.

Shelton and Stefani, 54, started dating in 2015 after they met when they were both working as coaches on the hit NBC series "The Voice." The couple live on the sprawling Ten Point Ranch near Tishomingo, where they wed on July 3, 2021 .

Stefani and Bush frontman Rossdale, who were married for 13 years, share three sons: Kingston, 18; Zuma, 15; and Apollo, 10.

Last August, Kingston, then 17, played his first public set inside The Doghouse music hall at Ole Red Tishomingo , performing a series of original alternative-rock songs. An encouraging Oklahoma audience of about 400 music lovers witnessed his debut, including McGaugh, and her mother, Lanell Eclair, also of Coalgate.

In addition to Kingston playing a few songs — as he exited the stage, the first-time performer was met by his smiling stepdad, who shook the teen's hand, hugged him and patted him on the back — last summer's show featured a solo set from Shelton. Stefani also joined her husband on stage to perform their chart-topping country duets "Nobody But You" and "Happy Anywhere" to close the Friday night concert, which Shelton teased a few days in advance on X, formerly Twitter .

For his debut at Ole Red, Zuma performed a more low-key and down-home show. At about 3 p.m. Monday, Shelton posted on X that he was planning to stop by Ole Red Tishomingo at about 5 p.m. that same day.

"I’m coming by to grab some food and thought I’d hop up and play 3 or 4 songs," he posted on the social media site.

McGaugh barely had time to drive from her Atoka workplace back to Coalgate, collect her mom and her daughter, Mazie McGaugh, and get over to Tishomingo. With the short notice, she said Shelton took the stage in the Ole Red restaurant, rather than the Doghouse music hall, for about 100 fans, mostly locals.

"We made pretty good time. It did dawn on me the other day ... 'He hasn't popped up at Tish in a while; I'd better be on alert because he may be gonna do that, because he does it once or twice a year.' You never know about him. But I never dreamed about it being on a Monday night," she said.

"I was shocked when he walked out. I was taken aback ... because I was like, 'Wait, he never has on a cowboy hat."

Along with the white hat, Shelton took the Ole Red stage in a blue plaid shirt, blue jeans and boots to perform "Playboys of the Southwestern World," a fan-favorite song he dedicated to his youngest stepson, Apollo. Stefani and Apollo watched the show at a table alongside the pop star's sister-in-law, niece and nephew. Both the boys wore cowboy hats, too, McGaugh said.

Shelton played "Pour Me a Drink," his new duet with Post Malone, solo before introducing Zuma. The teen took the stage dressed in a pale striped button-down shirt, blue jeans, brown boots and a black cowboy hat and carrying an acoustic guitar.

"This is Zuma, everybody," Shelton said, as the crowd cheered appreciatively.

"How y'all doing?" the teen drawled as he settled on a tall stool.

"Get the microphone where they can hear it," Shelton coached, adjusting the microphones for Zuma.

Strumming his guitar, Zuma sang solo on two popular songs by Bryan: "Oklahoma Smokeshow" and "Revival."

"Everybody was excited. I think everybody was very open with Kingston. But this was more of the vibe that's over there, the country music. It seemed like everybody knew every word, and it was very shocking how good his voice was. I had no idea. He was very good," McGaugh said.

"He may have been nervous, but you could not tell. ... Blake sat over on the side of the stage and watched it with a gigantic grin. He was so proud."

After earning rousing applause for his two-song set, Zuma yielded the stage back to Shelton, who closed the half-hour acoustic show with his signature song, "Ol' Red."

A Shelton super-fan. McGaugh said she's thrilled that she's now seen both Kingston and Zuma give their first public performances.

"I think those kids love it over here ... and everybody over here loves Gwen and her boys. They really do. I haven't ran into one person that said that they didn't like them, or that they weren't nice," she said.
