Justin Timberlake has confirmed a new collaboration with Mumford & Sons singer Marcus Mumford.
The pair have recorded a track for the new Coen brothers film Inside Llewyn Davis, which stars Timberlake and Mumford's wife Carey Mulligan.
"OK I can tell you this. There's a Coen brothers film coming out soon that I was lucky enough to work with Oscar Isaac and Carey Mulligan," Timberlake told Capital FM.
"And coincidentally I did work with Marcus Mumford on the soundtrack, so I became very good friends with them."
He added: "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."
Inside Llewyn Davis is expected to be released in cinemas later this year. (source)
