Blake SheltonandGwen Stefaniare still affectionate as ever.

On Friday, the “Make Me Love You” singer shared an intimate moment between the couple while relaxing on their tour bus.

In the retro-looking Instagram video, Shelton, 42, serenades his girlfriend of three years with an acoustic version of “Turnin’ Me On” — a song off hisTexoma Shorealbum that was written about Stefani.

“Pushing my buttons like it ain’t no thang,” Shelton sings in the video, as he lovingly stares at the 48-year-old pop singer. “If I’m what she wants, she gets what she wants / The neon’s buzzin’ when she pulls that string / Turnin’ me on like it’s her job / Sometimes I think she must get off on / Turnin’ me on, turnin’ me on.”

While he sings, Stefani turns the camera back on herself momentarily and is seen smiling at her man. TheL.A.M.B. designercaptioned the post: “I’m so grateful 🙏🏻❤️gx.”

Since they began dating in November 2015, the musicians have relied on their relationship as inspiration for several of their songs.

After releasingTexoma Shorein November 2017, fans immediately noticed that the Shelton’s track“Turnin’ Me On” was all about his romance with Stefani.

Co-written with Jessi Alexander and Josh Osborne, the song called back to Shelton and Stefani’s time “messing around.”There’s even a mention of Stefani’s “Revlon red” lips — a reference to the No Doubt frontwoman’s January 2017 partnership withRevlon as a global ambassador.

“Knows how to set me on fire / she’s always holdin’ the match / And when my body’s beside hers / there ain’t no turnin’ back,” Shelton sings on the track. “She’s Revlon red in the blackest night / lighting up the room in the world just like she’s turnin’ me on.”
