Maren Morris and Brothers Osborne took fans behind the scenes of their ACM Awards rehearsal, showing off a preview of their collaborative performance of "All My Favorite People" that will be featured on the show. From the rehearsal footage, it looks like it's going to be epic!

The microphone stands feature Morris' signature crown symbol, and the song's lyrics are epic: "All my favorite people are broken /Believe me / My heart should know / Some prayers are better left unspoken / I just wanna hold you / And let the rest go / All my friends are part saint and part sinner / We lean on each other / Try to rise above."

Morris explains that the ACM Awards are much more than just an award show. She says, "I love the ACMs because they feel like an award show/party/family reunion." She describes her collab with the Brothers as "a country affair."

The song is off of Morris' latest album Girl. While Morris was out on the road, tourmate Cassadee Pope filled in for the brothers' parts.

It's going to be a big night for the musicians aside from their performance. Morris is nominated for Female Artist of the Year; while Brothers Osborne are nominated for Duo of the Year,  Video of the Year for "Shoot Me Straight" and "Burning Man" (with Dierks Bentley), and Music Event of the Year for that same collaboration.
