The singer left the 'X Factor' band last year
According to the Mail On Sunday, a source said: “This book is going to be explosive and Simon Cowell will be furious with Zayn and may even try to stop it coming out.
“But Zayn is determined to reveal the secrets behind the clean image that was always so fiercely protected by the band’s publicity machine.”
The book is also expected to discuss some of Malik’s relationships, including his engagement to Little Mix‘s Perrie Edwards, who he met on the TV talent show, and his current girlfriend, supermodel Gigi Hadid.
Malik told The Fader earlier this year he had been unhappy with the music One Direction were making. “I wasn’t 100 per cent behind the music. It wasn’t me,” he said.
“It was music that was already given to us, and we were told this is what is going to sell to these people. As much as we were the biggest, most famous boy band in the world, it felt weird. We were told to be happy about something that we weren’t happy about.”
