The artist shared the title track of her sophomore album with crowds at the 58th Annual CMA Awards ceremony.
The high-profile collaboration was one of the stand-outs from Post Malone's ‘F-1Trillion (Long Bed)’ project earlier this year.
The song is set to feature on the alt-folk megastar's forthcoming ‘Unreal Unearth: Unending’ deluxe project.
The two-dozen-date tour will come to close with a show in the band's native Kentucky.
The fan-favourite duet appears on Post Malone's debut country album, ‘F-1Trillion’.
The fast-emerging folk artist debuted the track during her London, UK show at the OMEARA.
