Louis Tomlinson and Liam Payne may get along now, but it wasn't always that way.
In a recently released DVD extra from their This Is Us movie DVD, the One Direction singers reveal why they actually couldn't stand each other at first.
"We used to be at each other's throats while we were on The X Factor," Tomlinson says in the video. "He took it so, so seriously. But whenever I wanted to do anything slightly mischievous, he was always the daddy."
