One Direction always insist that they're just like brothers, but a major fight inspired their new song "Night Changes"! However, according to Jamie Scott, it wasn't the guys who were doing the fighting — it was their longtime songwriters.

“One of the songs on the record came from myself falling out with Julian Bunetta and John Ryan,” he told MTV. “One night, I came down to the studio, and three songs that I thought were sounding amazing when I left had been changed drastically through the night.”

However, he says the song doesn't have anything to do about their actual fight. It's more about the weird feelings you get staying up all night.

“The song is nothing about that, but the idea and the word came from me coming in the morning, because you get a bit delirious and you never quite know what you’re doing. But it was fine and all was resolved and we had a great song title.”

We agree! Especially after hearing that it's Harry Styles' favorite song on the album.

Plus, we are seriously excited to see what they're doing with their music video, especially after watching Louis Tomlinson get "arrested" while filming it. Like "Steal My Girl," we don't know where they're going with this craziness, but we can't wait to find out!
