Zayn Malik has admitted that he is still facing an ongoing battle with anxiety and self-confidence problems.

The 24-year-old former One Direction star, who opened up about his personal struggles in a candid interview last year after he cancelled a number of solo gigs, has revealed he's "working through certain issues".

"I always feel like I'm trying to work through whatever certain issues are around certain subjects," he said during a new video interview with Vogue.

"For me personally, it comes from a place of not wanting to come across as an over-arrogant person that takes themselves too seriously." he added.

The Pillowtalk singer said that despite being an international pop star, he struggles to mix with other people. 

"I'm not a very outgoing social person like in terms of a big group of people.

"You know when we're getting ready to put the second album out, people are going to start seeing me a bit more.

"I'm exciting for what people will think and I think it's been a year since I properly showed my face and stuff."

Malik, who appeared on the latest edition of the fashion bible with his girlfriend Gigi Hadid, also spoke about moving to America.

"When I first moved here, I was sleeping on a mattress for six months", he said. "I didn't really want to do anything to it because I liked the way it felt and it felt minimalistic, there was really nothing to hold onto."
