Kacey Musgraves surprised her audience in Nashville on Friday night by hosting her former tour colleague Harry Styles on stage to play "Space Cowboy" from her 2018 hit album Golden Hour .
Together Musgraves and Styles delivered a heartfelt duet of the track at the Bridgestone Arena concert of singer "Slow Burn", which was also the last tour date of their song "Oh, What a World: Tour II".
At the end of the song, Styles expressed his voice in gratitude for Musgrave's talent. "As a peer and as someone I like to call as a friend, it's always a pleasure to share the stage with this lady," Styles told the crowd. "She's made some of my favorite albums, and it's an honor to be here tonight to congratulate you and round off this wonderful tour and a wonderful year."
