The 23-year-old singer admitted he is naturally lazy and loves junk food and joked that he is going to have a "big belly" while on a break from the band.

He told Fabulous magazine: "I'm actually naturally very lazy. So I'm going to get a big fat belly. I'm going to be 24 soon and all these pies are going to catch up on me. You're going to see photos of me with a big belly."

Meanwhile, Niall Horan, 22, is planning to go backpacking with his friends during the hiatus.

He said: "I've spent the past few years of my life in planes and on tour buses and I've been through countries I've really loved but haven't had a chance to really see. I want to go back to Australia and definitely Thailand. With the band we stayed in luxury hotels but I want to see these countries like any lad of my age, just staying in hostels and that sort of thing. I don't want to stay at a Four Seasons. I've done that, I want something else.

"I did think about dying my hair brown so I won't get recognised, but I genuinely believe that if I'm on my own with my mates from home, no one will give me a second look."

However, despite claims to the contrary, they insist One Direction will be back after their break.

Liam Payne, 22, said: "It's not over. And yes, we're taking a break, but we need one. We have done four tours, five albums but we will be coming back. We don't want this to end."
