One Direction are so close, they think of one another as ''family'' rather than just friends or bandmates.
One Direction see one another as ''family''.
The 'Best Song Ever' hitmakers - consisting of Harry Styles, Niall Horan, Liam Payne, Zayn Malik and Louis Tomlinson - feel incredibly lucky to have developed such a strong relationship, which extends further than just friendship, in just three years.
Louis said: ''I think 'family' is probably the best way of describing us. It's different to friendship.''
Niall added: ''Yeah, we spend a good time on the road, and, obviously it's so important that we all get along or it won't work.''
Harry explained: ''There could have easily been one person who didn't get along with anyone; who nobody liked, but it wasn't like that.
''The relationship that's grown with these four boys that I didn't even know three years ago is absolutely insane and it's incredible. I'm very lucky that I get to spend so much time with them.''
Meanwhile, Harry, 20, has recently been rumoured to be embarking on a solo career, but he has shot down the speculation and insists he'll be part of One Direction - who shot to fame after taking part on 'The X Factor' in 2010 - until they're forced to go their separate ways due to old age.
He explained to TOTP magazine: ''I'm 100 per cent in this band. I still want to be touring with One Direction in ten years. I'll be doing it until I'm old and people are telling me to stop.''
