Luke Bryan has been teasing a mystery collaborator on his forthcoming album, Signs.

The secret has finally been revealed. It's Luke Combs and the song is "Finders Keepers."

Luke Bryan says, "I’ve always wanted to get him on a song. Obviously, he’s an amazing singer, and we’ve become buddies over the years. I’ve always wanted a Luke and Luke moment. The first time I heard this song, I was in the middle of recording in the studio, and my manager played me the song. It hit me like a ton of bricks from the moment I heard it, and I recorded it on the fly...When Luke heard it, he called me right back and said, ‘let’s do this thing.’”

Signs comes out September 18th.
