Popsugar Entertainment Music Tours Watch Kacey Musgraves and Harry Styles Sing "Space Cowboy" Harry Styles Reunited With Kacey Musgraves to Sing "Space Cowboy" — Be Still My Heart 28 October 2019 by Karenna Meredith First Published: 26 October 2019 Kacey Musgraves closed out her "Oh What a World" tour on Friday, and she gave the audience an unforgettable night, thanks in part to Harry Styles. The "Lights Up" singer surprised the Nashville crowd when he and Musgraves performed "Space Cowboy" together — and Styles even worked in a little "Yee-haw!" at the end. "As a peer, and someone I like to call a friend, it's always a pleasure, an honour to share the stage with this lady," Styles told the audience. "She's made a couple of my favourite albums, and it's an honour to be here tonight with all of you to say congratulations and round off this wonderful tour, and a wonderful year." Musgraves and Styles are used to touring together, since she opened for his North American tour back in 2018. During that time, they performed a duet of Shania Twain's "You're Still the One" at Madison Square Garden, which sent the internet into a tailspin. Looks like things haven't changed much — keep reading to see a few of our favourite Twitter reactions to the duo's dreamy performance below.
