Gwen Stefani turned to social media on Friday (Sept. 21) to share a private moment with her boyfriend, Blake Shelton. In the video above, which she posted to Instagram, Shelton gives Stefani a private performance of his sultry song, "Turnin' Me On."

The couple are seated in back-to-back plush seats on a tour bus in the video, with both of them dressed casually. Shelton looks over at Stefani repeatedly as he sings his current single, and she turns the camera back and forth between him and herself as he sings, ending with a sly smile into the camera.

"I'm so grateful," she writes to accompany the video.

"Turnin' Me On" is the third single from Shelton's most recent album, Texoma Shore. Shelton co-wrote the song with Jessi Alexander and Josh Osborne, and the lyrics are an unabashed celebration of desire.

"She's turning me on, turning me on / Pushing my buttons like it ain't no thing / If I'm what she wants, she gets what she wants / The neon's buzzing when she pulls that string / Turning me on like it's her job / Sometimes I think she must get off on / Turning me on, turning me on," he sings in the chorus.

There's also a reference to Stefani's signature red lips, which earned her an endorsement with Revlon: "She's Revlon red in the blackest night."

The couple's musical and personal lives have intertwined several times before, including duets on "Go Ahead and Break My Heart," which appears on Shelton's If I'm Honest album from 2016, and "You Make It Feel Like Christmas," the title song of Stefani's 2017 holiday album.
