Louis Tomlinson told Top of the Pops magazine (via EntertainmentWise) recently that the 1D guys are so tight (take that, breakup rumors) that they're more of a family than just friends. He explained, "I think 'family' is probably the best way of describing us. It's different to friendship."
Niall Horan chimed in with his take on their lovefest, saying, "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." Good point, Nialler. You wouldn't want any drama during all that time on the road.
Harry Styles weighed in on how lucky they are to get along so well, explaining, "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."
