Gwen Stefani, Blake Shelton to debut duet

Blake Shelton has announced that he and girlfriend Gwen Stefani will be taking the stage during next week's episode of "The Voice" to perform their duet for the first time.
"SOOO.... I'm performing next week on @NBCTheVoice," the 39-year-old country star wrote on Twitter.
"I'm performing with @gwenstefani. We're performing a song off my album we wrote together."
Stefani, 46, was the first to confirm rumors of a musical collaboration when she tweeted a picture of the cover art for Shelton's new album, If I'm Honest.
"Look what I found lying round the house! ??#ispymyname #goaheadandbreakmyheart?? @blakeshelton #eeeekkkk! #crazy!?? Gx," she wrote back in April.

The next episode of "The Voice" airs on May 9.
