In October, Blake Shelton revealed the cover art and track list for his upcoming album, Fully Loaded: God’s Country, which drops on Dec. 13.

Today (Dec. 4), Blake revealed that one of the new tracks, “Nobody But You,” is a duet with girlfriend Gwen Stefani. Penned by Ross Copperman, Shane McAnally, Josh Osborne and Tommy Lee James, “Nobody But You” is one of five new tunes on the upcoming album.

“This was one of those songs where the more I heard it, the more I fell in love with it,” Blake says. “I also realized how important it is for me and where I am in my life, and I think that’s why Shane [McAnally] was trying to get it to me. It fits my story. I was about to go in and record when I decided that it needed Gwen on it—because it is our song. I think it’s magic.”
