Gwen Stefani's son Zuma is Blake Shelton's twin! See the aspiring country singer

Gwen Stefani's son is looking like Blake Shelton's twin!

The "Hollaback Girl" hitmaker posted an Instagram tribute for her middle son Zuma's 17th birthday Thursday, Aug. 20, and one sweet snap features the star's son with his famous stepdad.

Stefani captioned the post, "happy birthday to our sweet and talented Zuma!! we love u soooo much!! ❤️"

Zuma – who seemingly wants to be a country crooner like Shelton – sported matching western shirts and cowboy hats in the picture, rocking the same type of mullet as the "New Country" collaborator at the start of his career.

Stefani also shared a video of Zuma (who she shares with British rocker ex Gavin Rossdale) singing a cover of Zach Bryan's 2024 song "Dawns" featuring Maggie Rogers. Last year, Stefani opened up about her children finding their own musical tastes.

"I look at my kids and see them discovering music and I'm like, 'How did you find ‘80s music?' Of course they would have heard it in the house or the car, but the 'you might also like' (algorithm) is out there a lot," Stefani said.

In 2023, the star stunned with her three sons and husband Shelton during her Hollywood Walk of Fame ceremony. As they celebrated the Grammy-winning No Doubt singer and "The Voice" coach, Shelton praised Stefani for her approach to balancing life and work.

"It was clear to me that she was a mother, first and foremost, over anything else in the world," Shelton said of first meeting her in 2014. "And now standing here, almost 10 years later after I first met her, I can say without question that being a mother is still the most important thing in her life." Stefani also has sons Apollo, 11, and Kingston, 19.
