The former One Direction star - who has posted a picture of the single's cover on social media - has promised his legions of fans that they won't have to wait much longer to hear the record.

Zayn revealed the track is a duet with rapper PARTYNEXTDOOR and when he was asked by one Twitter user when it will drop, Zayn replied: "Soon and I mean it."

Subsequently, another Zayn fan questioned whether he would stick to his own deadline and the 24-year-old star said: "Don't be like that ... I promise you (sic)"

Despite the doubts of his fans, Zayn has been working diligently since he left One Direction to establish himself as a solo artist.

The dark-haired hunk released his first solo album, 'Mind of Mine', in March last year and now appears to be on the cusp of releasing new music in the coming weeks.

The success of Zayn's debut album also came amid his troubles with anxiety, which caused him to withdraw from a number of planned performances.

Meanwhile, Zayn - who is dating model Gigi Hadid - recently admitted he has no idea why he was known as the "mysterious one" when he was in One Direction, alongside Niall Horan, Liam Payne, Harry Styles and Louis Tomlinson.

He said: "I have no idea why. It was obviously a marketing strategy to appeal to different areas of female personalities and wants and needs. 'I might want a cute one', 'I might want a cheeky one', 'I might want a mysterious one', that's all it was.

"It's cool, that's life, I guess. I don't really think of myself as mysterious, but maybe I am."
