The pop star revealed the track listing for her new release, "Lover", on Friday, August 16, and as well as her "ME!" duet with Brendon Urie, the album will feature "Soon You'll Get Better", featuring Natalie Maines and her bandmates.
There are no details about the tune, but many fans believe it's all about Swift's mum, who is battling cancer.
Taylor previously hinted there would be a Dixie Chicks collaboration coming by featuring a photo of the trio in her "ME!" video and wearing a band badge for her Entertainment Weekly cover shoot.
"Lover" is released next week, August 23.
