Clearly, no one is a bigger fan of Maren Morris than her fiancé Ryan Hurd, and this adorable video proves that.

At a recent show, a friend of the couple captured the video of Hurd, unbeknownst to him, rocking out to his girlfriend's set, singing along to every word of her sassy track, "Rich." An up-and-coming singer himself, Hurd could not be more into the performance, jamming to the music and showing off his best moves with a red Solo cup in hand. "Every promise you made me would have some real value / 'Cause all the little lies rolling on your lips / Is money falling from the sky (ka-ching, ka-ching)," Hurd sings along in the clip, enjoying every moment of the show.

"I think I located my biggest fan. This warmed my heart," Morris writes alongside the video.

The couple got engaged in summer of 2017, and while a specific wedding date has not been shared, they are thinking of a spring wedding before they both start touring. Hurd went all out on his engagement ring for Morris, having the ring itself custom-made in Canada with an uncut diamond from New York.

“Oh, I sobbed. I mean it was so emotional and so perfect,” Morris tells Entertainment Tonight about the special moment. “He’s a very thoughtful human being, and I feel like the proposal was just as thoughtful as he always is. So it was perfect.”

Morris scored three nods at the 2017 CMA Awards, one for Female Vocalist of the Year, and two with Thomas Rhett for their hit collaboration, "Craving You," earning nominations for Music Video of the Year and Musical Event of the Year. She's also set to hit the road with One Direction star Niall Horan as an opening act on his 2018 Flicker World Tour.
