Gwen Stefani and Blake Shelton are in the holiday spirit.

The “Hollaback Girl” singer and the country star put on an impromptu performance of their holiday hit “You Make Me Feel Like Christmas” and shared it on TikTok on Saturday, Dec. 21.

In the video, Stefani, 55, sits up on her couch while Shelton, 48, leans on her, and she happily gives him his cue to start. A smiley Shelton then begins strumming his guitar as Stefani kicks off the song’s lyrics.

“It barely took a breathe to realize / We’re going to be a classic for all time / I want to thank you, baby / You make it feel like Christmas,” Stefani sings.

Then, the sweet couple begins to sing together.

“Sweet gingerbread made with molasses / My heart skipped and I reacted / Can’t believe that this is happening / Like a present sent from God,” they sing. “Sleigh bells singing Hallelujah / Stars are shining on us too.”

“I want to thank you, baby / You make it feel like Christmas,” they conclude, as Stefani brings the camera close to her face and kisses everyone goodbye.

“You Make It Feel Like Christmas” was featured on Stefani’s 2017 album of the same name.

In 2018, the pair released a campy music video for the song, where they live in a Christmas fantasy complete with tuxedos, ball gowns and plenty of old Hollywood glamour.

The pair also performed the song live during the 2022 Rockefeller Center Christmas tree lighting.

In addition to “You Make Me Feel Like Christmas,” the pair has worked on several duets together over the years. Most recently, they collaborated on “Purple Irises,” which was featured on Stefani’s latest studio album Bouquet.

“He loved the song so much, he was like, ‘Save that one.’ I asked, ‘Wait, do you want to hop on the song?’ Because I would never dare ask — he gets so many requests,” Stefani recently told PEOPLE.

They also recorded “Go Ahead and Break My Heart” in 2016, “Nobody But You” in 2019 and “Happy Anywhere” in 2021.

“We want to do everything together,” Stefani added. “We’re besties.”
