Bruno Mars has said that it only took 'one or two hours' to write 'Forget You'.
Speaking exclusively to us, he revealed that he had a lot of fun collaborating with Cee-Lo Green on the track.
'That track would not have happened if Cee-Lo was not in the room,' he revealed.
'I was a big fan of Cee-Lo and wanted to work with him for a long time. He was on Travie (McCoy)'s album, which I produced, he's on my album.
'We became so comfortable that everytime we were in the studio (together) it was like 'The Comedy Store', we'd just be laughing, writing songs.
'We were just jamming. I was on piano and kept on repeating '**** you'. Within an hour or two we'd written the whole song with us going back and forth.'
He then joked: 'I should have kept the damn song!'
