Justin Timberlake and Marcus Mumford have formed a partnership to put together a movie soundtrack.
The singers have teamed up to record the music for Coen Brothers film "Inside Llewyn Davis"
JT confirmed the duet with the Mumford in an interview.
Justin said: "I did work with Marcus Mumford on the soundtrack.
"Marcus and myself, we all kind of worked on the music together and I don't know any other world where we would have the opportunity to collaborate like that but it was so much fun.
"So not only will that be a great movie, but the music to it will be fantastic."
The film, which is due for release later this year, stars Marcus's wife Carey Mulligan.
