This isn't the first time that Shelton and Stefani worked together. The Voice coaches collaborated on the song "Go Ahead and Break My Heart."
ET spoke with Stefani last year about her experience writing the track with her significant other.
"Anytime I've ever collaborated with anyone, it's always my favorite," she admitted. "But to do something with him -- because he's so talented and comes from such a different world -- to make music together, it was just so shocking! So amazing to do it live and share it with everybody."
