Calvin Harris has revealed that the Leona Lewis version of his Rihanna chart topper 'We Found Love' is an X Factor-esque ballad.

Leona Lewis recently revealed that she had recorded the track with Harris long before Rihanna recorded her version of the track - which went on to become a No.1 hit across the globe. However, the club anthem could have sounded very different if Lewis' version had been released.

"They're very different because [Leona] sings it dead softly, you know, how Leona sings," Harris told Kiss FM in a recent radio interview. "It's more like an X Factor ballad."

But for fans hoping to hear the track might be out of luck - with Harris revealing that he and Leona are the only people to own a copy of the track.

He adds: "The only people that have got it are me and Leona Lewis."

Speaking recently to The Daily Star of her version of 'We Found Love', Lewis claimed that her version was the superior song.

"I didn’t commit to it because I wanted 'Trouble' to be my first single so I think that was another reason they went with Rihanna," she told the tabloid. "It was the same version and production but mine’s better."

Calvin Harris this week secured his place as one of the world's biggest dance stars, as his new album 18 Months took the UK album top spot. The album, featuring collaborations with Kelis, Tinie Tempah, Ne-Yo, Ellie Goulding and of course, Rihanna, hit No.1 in this week's new album chart.
