Blake Shelton and Gwen Stefani’s romantic duet “Nobody But You” has peaked at No. 1 on Billboard’s Country Airplay chart for the week ending on May 2. To celebrate the accomplishment, “The Voice” judges took to Twitter.

“Congratulations @gwenstefani on your first country song going #1 at country radio!!!” Shelton wrote to his lover. “Not bad for your first try!!!!! Thank you all as well!!! #nobodybutyou”

The singer’s tweet received over 600 retweets and over 11,700 likes at press time. Among those to react to his tweet was Stefani.

“Trying to wrap my head around the fact that I even get to know you Blake Shelton [heart eyes emoji] -let alone be on Such a beautiful classic duet w u?! [mind explosion emoji],” she wrote. “thank you ! for taking me along on this ride with you!! I am so grateful and blown away by all the support everyone has shown us!!?!! [blushing emoji, prayer hands] gx”

Her response received over 300 retweets and nearly 5,000 likes at press time. The duo released an acoustic version of the track as well as a visual on March 20.

As previously reported, it is rumored that Shelton and Stefani had a secret backyard wedding on the “God Gave Me You” singer’s ranch in Oklahoma. However, Star Magazine’s reputation for publishing gossip based on the accounts of unreliable sources doesn’t give this rumor much weight.

Shelton and Stefani have been dating for around five years. Their relationship followed his divorce from Miranda Lambert and her ongoing divorce from Gavin Rossdale.

The two performed “Nobody But You” for the “ACM Presents: Our Country” special on April 5.

“We happen to be in Oklahoma, hiding away from everybody, doing what we're supposed to do. And, we're also doing what I think everybody else must be doing, which is... drinking all day,” Shelton began.

“Not me! What are you talking about?” Stefani jokingly replied while sitting down a glass of wine.

The show served as a replacement for the Academy of Country Music Awards, which was postponed due to the coronavirus pandemic.
