Blake Shelton and Gwen Stefani Perform a No Doubt Song Together at ACM Awards After Party -- Watch!

The couple also had an adorable date night at the Las Vegas awards show on Sunday.

Blake Shelton and Gwen Stefani’s adorable date night at the Academy of Country Music Awards in Las Vegas on Sunday didn’t end when the awards show was over!

The couple also hit the stage together at Shelton’s “BS and Friends” after party show at the Mandalay Bay House of Blues, where Stefani came out for a surprise set. She performed “Hollaback Girl,” and, at Shelton’s request, her No Doubt track, “Hella Good.”

"Will you do it with me?" Stefani is seen asking her beau in a fan video after he asked for the song.

“I know it's weird that I'm here,” she told the country-loving crowd, “but we all have one thing in common -- we all love Blake Shelton!"

Shelton then joined Stefani on stage as the band played the song, and the two shared a kiss at the end of Stefani’s set.

"I didn't think this was ever gonna happen!" the No Doubt frontwoman remarked, pointing to Shelton. "Sexiest man alive!"

Stefani shared some pics from the star-studded after party, which also included performances by Shelton himself, as well as pals Kelly Clarkson, Luke Bryan and more. The 48-year-old singer even posted a boomerang shot of her beau singing, which she decorated with a heart, as well as a clip of Clarkson’s set.


The sweet impromptu duet wasn’t the only musical moment the couple shared on Sunday, however. Stefani was also spotted singing along to Shelton’s performance of “I Lived It” during the ACM Awards and afterwards gave him a beaming standing ovation.

Though the couple skipped the ACM red carpet, they posed for pics in the audience together, with Shelton rocking a gray blazer, black button-down shirt and jeans, while Stefani stunned in a short crimson dress with black knee-high boots and her long, straight blonde locks cascading over her shoulders
