Zayn has blasted One Direction for what they did to him when he left the group

However, four years on from becoming a solo artist, and Zayn still has hard feelings towards Harry Styles, Louis Tomlinson, Niall Horan and Liam Payne.

To be more specific, Zayn has told British Vogue that he left 1D without making a "single friend," adding that "I have always been a bit like that, though — always a bit of an island. I don't like to confer with too many people."

So it might not come as a surprise that when asked if still keeps in touch with any of them, he answered, "Nah".

"I ain't spoken to any of them for a long time, to be honest with you," he says. "That's just the way it is."

While he didn't go into exact detail as to why he hasn't kept in touch, he did throw some shade their way by revealing how he felt he was treated when he left the band.

"There are things that happened and things that were said after I left... Snide things. Small things that I would never have expected."

But he understands that it wasn't a normal situation for any teenage boy to be thrown in, and expect to come out as best friends.

"We went from theaters, 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 effects you a little bit," he reveals.

"People take it different ways — especially when there are five different personalities. The relationships had broken apart."
