Singer-songwriter Ed penned a track for the boys' first album, Up All Night, and has previously spoken about his friendship with Harry. 

He told Xfm: 'I have a tune that I think they're recording for their album that I wrote. They're really cool guys. 

'Harry's a lad - I was with him last night actually. Being in music you're quite segregated from everyone and you're always busy doing promo.

'When you're on the same promo run as someone or in the same kind of situation as someone you grow quite close, friendship-wise. He's a very cool guy.'
