From feud to duet: Musgraves and Lambert team up on a new album track

Kacey Musgraves reveals that her song Mama's Broken Heart was pitched to Miranda Lambert without her knowledge, fueling a rumored feud after Lambert recorded it for Lambert's 2013 Four the Record; Musgraves later wrote Merry Go Round, and the two have since reconciled enough to collaborate on a track for Musgraves' upcoming album Middle of Nowhere, due in May—a full-circle moment that leads to a joint song on the project.
