On Saturday, Shelton is partnering with Encore Drive-In Nights to host a one-night-only cinematic concert event, featuring Stefani and Trace Adkins.

“This is such a great way to enjoy music with your family and friends and stay safe,” he said. "I'm excited we're getting the chance to perform a concert for fans, and we're going to go back and play old hits like 'Austin,' newer songs like 'God's Country,' and we might even introduce something brand-new! So fill up those popcorn tubs and get ready for some country music."

As "Nobody But You" hit No. 1 on the Billboard Country Airplay chart in April, Shelton celebrated pop star girlfriend's first chart-topper in the country genre.

Shelton congratulated Stefani on the success in a sweet tweet at the time. "Congratulations @gwenstefani on your first country song going #1 at country radio!!! Not bad for your first try!!!!! Thank you all as well!!! #nobodybutyou," he wrote.

Stefani responded with her own adoring note: "Trying to wrap my head around the fact that I even get to know you Blake Shelton-let alone be on Such a beautiful classic duet w u?! thank you! for taking me along on this ride with you!!" she added. "I am so grateful and blown away by all the support everyone has shown us!!?!! gx."
