Grab the tissues, it’s a weeper!

British singer-songwriter Calum Scott has teamed up with Leona Lewis for a new version of his latest single You Are The Reason, which is a powerfully emotional ballad.

The song is largely the same as Calum’s original, save for Leona’s angelic vocals added on the verses and chorus.

Calum released the music video for You Are The Reason last month, and the visual has already been watched more than 41 million times on YouTube.

“You Are The Reason started out as a song about something completely different than what it is now,” Scott explained.

“It was originally written from a fragile place of anxiety and not knowing the cause of it, so the song started to become Without A Reason.

“But as we carried on writing, we realised how every relationship has difficult times but you stick with it because the love you fundamentally feel for the other person overrides everything else.”

He added: “I wrote this song to say thank you to those special people who make our lives better, simply because they’re in it.”

It follows his huge breakout hit Dancing On My Own, which was a stripped down version of Robyn’s classic and has been streamed 500 million times so far.

It also comes after his original single Rhythm Inside, which has been streamed over 24 million times worldwide.
