Gwen Stefani has been surprised by her return to 'The Voice'.

The 53-year-old singer is returning to the show to star alongside John Legend, Niall Horan and Reba McEntire, and Blake Shelton – her husband, who is leaving 'The Voice' – has revealed that she never expected to be invited back.

Blake, 46 – who married Gwen in 2021 – told PEOPLE: "When I finally came to the conclusion that I was going to call it a day last year, you know, she even said, 'Well, I guess they probably won't have me back ever again.'

"And I go, 'What are you talking? They invited you to be a coach for seasons before you and I were ever thing.' And she goes, 'Oh, yeah, that's right. They did do that.' I go. 'Yeah, I'm pretty sure they're still going to want Gwen Stefani to be a coach.' Then sure enough, you know, she's already gonna be back and she was excited to get the call."

Blake and Gwen previously went head-to-head during their time on 'The Voice'.

And the country music star has admitted to being a huge fan of his wife's coaching style, describing her as a "visionary".

The 'Came Here to Forget' hitmaker – who was previously married to the award-winning country star Miranda Lambert – said: "She's just really comes at coaching in a way that I don't think anybody else has done still and there's been a lot of coaches.

"But she's such a visionary, and that comes through with her artists. You can see these kids come on the show … by the end they actually look like stars, and that's the Gwen Stefani effect."
