UK based boyband One Direction have revealed that when they were first put together by music mogul Simon Cowell, they didn't see eye-to-eye and there was something of a clash between two of the members.

In the special features section of the DVD release of their movie, 'This Is Us', Liam Payne jokes: "The funniest thing now is that me and Louis did not get on at all. We were two completely different characters. He was so loud and bubbly, and there was one point where I literally wanted to whack him."

Louis Tomlinson then explained that Payne has a tendency to be incredibly serious and his stern manner has earned him a nickname within the group: "We used to be at each other's throats while we were on the X Factor. He took it so, so seriously."

"But whenever I wanted to do anything slightly mischievous he was always the daddy. That is why he got the nickname Daddy Directioner. He is the dad who you trust to book your holiday."

Irish heartthrob Niall Horan added that Tomlinson's fun-loving and silly nature gives the boyband the life they're known for so they're glad to have a varied dynamic among them: "If it wasn't for Louis, we'd be the most boring band in the world. But at the same time he knows the balance between getting the job done and having a laugh."
