During Maren Morris’ sold-out show at Nashville’s Ryman Auditorium on March 13, Miranda Lambert, Cassadee Pope, Brandi Carlile and Natalie Hemby surprised Maren by joining her onstage to sing “My Church.”

“This moment was not planned but it made my 🖤 explode,” said Maren, in part, via Twitter.

Earlier in the evening, Brandi teamed with Maren to sing “Common,” their duet on Maren’s new album, Girl. Next, Maren was joined by Cassadee—who opened the show—to sing “All My Favorite People,” a duet on Girl that features Brothers Osborne. Later, Miranda and Natalie joined Maren onstage to sing “Virginia Bluebell,” a Natalie co-penned cut from Miranda’s 2009 album, Revolution. The trio also joined forces to sing “I Wish I Was,” which Natalie also co-penned for Maren’s 2016 album, Hero.

Watch Maren, Miranda, Cassadee, Brandi and Natalie collaborate on “My Church.”
