Blake Shelton and Gwen Stefani’s duet, “Nobody But You,” ascended to No. 1 on the Billboard Country Airplay chart this week. The single is Blake’s 27th No. 1 hit on the country chart, while Gwen notched her first No. 1 on the country chart after more than 25 years as a star—both as a solo artist and fronting No Doubt—on the pop charts.

Penned by Ross Copperman, Shane McAnally, Josh Osborne and Tommy Lee James, “Nobody But You” is one of four new tracks on Blake’s 2019 album, Fully Loaded: God’s Country.

“I knew the moment I heard this song that I wanted to record it,” says Blake. “Shane McAnally, Ross Copperman, Josh Osborne and Tommy Lee James, you wrote a perfect song in which every lyric has meaning in my life, and I thank you. Another thanks goes to the fans who continue to listen—and I know there are a lot of distractions these days—one day soon we can all celebrate music together again. And finally, thanks to Gwen for joining me and making this one of the most special songs I’ve recorded. Congratulations on your first number one country single!”
