Lambert who recently married an NYPD officer joined Morris on stage for the grand finale.
Maren Morris had surprises planned for her Ryman Auditorium show in Nashville Wednesday night: Miranda Lambert and songwriter Natalie Hemby. The trio performed two songs including "Virginia Bluebell," a deep cut from Lambert's "Revolution" album.
"I love Maren Morris. She's a bada--!" Lambert told a shocked crowd, praising her fellow Texan.
Hemby co-wrote "Virginia Bluebell" with Lambert and also co-wrote Morris' "I Wish I Was," the next song they performed, from Morris' acclaimed debut album, "Hero."
"It says in the chorus of that song, 'I'm not the hero in this story.' I just think about the headspace I was in the day I wrote that song, where I'm basically having to end a relationship and be the bad guy and how far I've come since that day," Morris told Taste of Country Nights in 2016. That song is the reason she named her first album "Hero."
