Ed Sheeran has revealed his hotly anticipated collaboration with Eminem was put together in the house of an equally famous friend - Russell Crowe. 

The 'Shape of You' singer was one of the star-studded line-up of guest singers featured on the track listing for Eminem's upcoming ninth album, Revival.

Backstage at Jingle Ball in New York City on Friday night (local time) Billboard asked Sheeran just how the collaboration on the song 'River' came about. 

"I sound like such a c**t name-dropping, but I was traveling Australia and Russell Crowe has a house, this big farm," Sheeran explained. 

He said the Gladiator actor told him he was welcome to stay in the house and use its recording studio while he was away. 

"I get an email from Paul Rosenberg, Eminem's manager, and he said, 'We're going to start putting the album together, send any ideas,'" Sheeran said. 

"So I used the studio at Russell's house - played the drums on it, and then played the guitar, and then recorded the thing and wrote the chorus and did the piano on it, and then sent it off and then didn't hear anything back. This was March 2016."

Sheeran said a year later while travelling in Mexico he heard from a friend who regularly produces for Eminem that the rapper had put some verses to it. He also revealed he always had ideas for collaboration in the back of his mind, just in case he ever got the opportunity. 

Sheeran described the rapper as "such a sweet, talented guy", adding the experience was "a door that I thought was closed and just opened randomly".

Revival is due for release December 15.
