He tells the magazine that he is no longer mates with the other members of One Direction.
"Nah. I ain't spoke to any of them for a long time, to be honest with you. That's just the way it is. There's things that happen and things that were said after I left... Snide things. Small things that I would never have expected."
But he also says they were never really friends to begin with.
"We went from theatres, to arenas, to stadiums - there was never any sort of bridge between. Just boom, boom, boom.... I guess that kind of progression to any mind – but especially when you're 17, 18 - it kind of affects you a little bit. People take it different ways – especially when there are five different personalities. The relationships had broken apart."
