UK boyband Blue, who are currently starring in ITV's 'The Big Reunion' alongside other newly reformed pop acts, have revealed that 5ive used to fight with each other a lot backstage.

'All Rise' singer Duncan James told Now! magazine that he remembers when the members of the other group used to scrap backstage and then put on a front in order to perform together in public:

"We watched back the videos of 5ive and they used to throw each other down the stairs and kick the s**t out of each other. Then they'd get on stage and do a gig."

Speaking about the tension in his own group, Blue, James added: "Our battles were more about ourselves and learning who we are as individuals."

Meanwhile, Blue tweeted a message to their fans to let them know it will be disappointing when 'The Big Reunion' comes to an end because they've enjoyed it so much: "We will be #HurtLovers when the #BigReunion comes to an end on @itv2 - it's been fun. Loved the banter!"
