Miranda Lambert joined her friend and country breakout star Ashley Monroe onstage in a small Nashville club on Wednesday, two days after announcing her split from Blake Shelton.

Monroe was performing at the venue the Basement as a preview to her upcoming album, The Blade, due out Friday. She brought Lambert up on stage to sing her track, “Heart Like Mine,” during her encore performance. The two wrote the song for Lambert’s Revolution album, and Lambert also appears on The Blade‘s title track.

Lambert and Shelton announced their divorce after four years of marriage on Monday. Lambert’s next solo show will be July 28 in Nashville.
