Before she came onstage, the "God's Country" performer told the crowd about how he's been working to strengthen his guitar skills and licks from "Sweet Home Alabama" as well as a Garth Brooks song before launching into "Don't Speak."

The audience cheered as Stefani made an entrance to sing the Grammy-nominated 1996 track, crooning the lyrics: "Don't speak, I know just what you're saying / So please stop explaining / Don't tell me 'cause it hurts."

"This is Gwen Stefani, everybody!" Shelton excitedly told the crowd after the performance, per a fan video shared on YouTube.

The couple then sang "Nobody But You," sharing a sweet hug and kiss after the performance and holding hands as they walked to the back of the stage to deliver a rendition of "Happy Anywhere."

In a December cover story interview with PEOPLE, Shelton spoke about enjoying simple times with Stefani at home.

"Gwen and I have done so much traveling and touring and work the first half of our lives that now we're like, 'Hey, I'm good to put my sweatpants on at 6 p.m. and watch Ozark eight times,'" he said at the time. "That's our life now, and we love it."
