Huffington Post exclusively reported today that Johnny and Marilyn have recorded a duet of Carly Simon's 1972 hit song, "You're So Vain."
The cover will be featured on Marilyn's upcoming eighth studio album, Born Villain.
Johnny, who does have a bit of a musical background himself, featured one of Marilyn's song, "The Nobodies," in his 2001 film, From Hell.
We wonder if this new collaboration will also be featured in one of Johnny's films?
We can't wait to hear what it sounds like!
Born Villain is set to be released on May 1.
