One Direction are so close, they think of one another as ''family'' rather than just friends or bandmates.
The X Factor finalists 2010, consisting of Harry Styles, Niall Horan, Liam Payne, Zayn Malik and Louis Tomlinson, feel closer than ever.
Speaking to TOTP magazine, 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.''
