Chris Martin has revealed Beyoncé "politely showed Coldplay the door" when they asked the singer to duet with them, the Daily Mail reports.

The frontman, 39, explained the superstar, 35, declined the group's first offer, before eventually agreeing to work with the hitmakers on Hymn For The Weekend in 2015.

Chatting to Graham Norton on his Friday night talk show, Chris said: 'We've been to her before and were politely shown the door.

"I had a tiny idea for a little song and when I asked her if she wanted to do it she said no. We then went to her with a more real song and she was very sweet and sang it."

The song featured on Coldplay's most recent album A Head Full Of Dreams and was released as a single last year, with Beyoncé lending her vocals to the track and performing in an elaborate outfit in the music video.

When asked further about the album - which is the group's seventh release and according to Chris could be their last - the musician said: "It's a way of looking at the world in a more optimistic manner.

"It's not saying everything is great all the time, it's more about understanding what has happened to you and not be depressed."
