Country duo Dan + Shay made hearts flutter last week when they turned to Facebook to share an acoustic cover of the Carrie Underwood hit, "Heartbeat," which features Sam Hunt.

"Dancing to the rhythm of this Carrie Underwood song, always," the pair captioned the picture.

In addition to receiving over 150,000 views and counting, they had a pretty well known fan who loved the rendition: Underwood herself. She shared the video on her own Facebook page to show her admiration for their work.

"Love this! Thanks Guys!" she says of the video.

Now, no one can sing the ballad quite like Underwood and Hunt, but the boys came pretty close. They perfectly executed each note, as well as the harmonies that take the tune to new levels.

It's been a pretty big time for Dan + Shay. In addition to being endorsed by Underwood, the boys have announced a headlining fall tour to promote their latest album, Obsessed, and earned a No. 1 hit on Billboard's Country Airplay chart for their single “From the Ground Up.”

"We have been so humbled by the response to our new album and can’t wait to perform live for our fans this fall,” says Dan Smyers. “Our fans inspired the title of the Obsessed album, so it was only fitting to name the tour after the album.”

The trek will make 15 stops beginning in November, and last through mid-December. The tour will kick off in Colorado and make its way from coast to coast before wrapping up in Boston.
