This may be one of the most highly-anticipated songs of the year.
Music's hottest power couple Blake Shelton and Gwen Stefani are expected to release a duet together on the country singer's upcoming album (his new single "Came Here to Forget" is out Tuesday), a source tells PEOPLE exclusively.
While details of the song are still under wraps, the pair clearly work seamlessly in their professional lives. After first meeting Shelton in 2014 during her first stint as a coach on The Voice, the rocker is back this season as her boyfriend's advisor.

"Both of them share a passion for music and have lately been very busy in the studio," says another insider. "They seem very supportive of each other's careers."
Just two months before the singers began dating, Shelton told PEOPLE he couldn't imagine ever jamming with Stefani. "I don't know musically what Gwen and I would probably ever have in common," he said, laughing. "I don't ever see Gwen and I sitting down and writing songs."
Oh, how things have changed!
