In spite of the rumors surrounding Blake Shelton and Gwen Stefani, the two's relationship is remaining strong. The 48-year-old former No Doubt's frontwoman even shared a video on Instagram over the weekend while her man was serenading her, proving they are deeply in love with each other.

The clip started with Shelton's voice singing in the background. Gwen was holding her smartphone while they seemed to be inside a tour bus. In one moment, the "Hollaback Girl" hitmaker panned the camera to her boyfriend's side.

Shelton was seen strumming his guitar while looking straightly at Stefani and seemed to be serenading her. Gavin Rossdale's former wife then returned the camera's focus on her and smiled from ear to ear while also staring back at him.

Shelton was singing his new song, "Turnin' Me On," from his album "Texoma Shore." The track is said to be about his relationship with Stefani.

"Pushing my buttons like it ain't no thang," Blake sang while looking at Gwen, who was staring back at him. "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."

According to People, Shelton wrote "Turnin' Me On" with Jessi Alexander and Josh Osborne. It is a callback to the time the "The Voice" judges were still "messing around." The song even has the lyrics about Stefani's "Revlon lips," referencing her partnership with the brand as a global ambassador in January 2017.

Aside from "Turnin' Me On," Shelton's other song, "I'll Name the Dogs," is also inspired by Stefani. The track is about a couple who decided to get married and to live together. Although the two are yet to tie the knot, Miranda Lambert's former husband revealed he is already thinking about marriage.

Stefani, on the other hand, also has a few songs inspired by Shelton. It includes her 2016 song, "Make Me Like You" from her album "This Is What The Truth Feels Like," and "If I'm Honest" from her 2017 holiday record "You Make it Feel Like Christmas."

Of course, fans celebrated Shelton and Stefani's serenade video and cannot help but gush over their sweet moment. "I love you two together," one fan commented, per Life & Style Magazine. "You both deserve to be happy after what you've been through."
