Zayn Malik writing tell-all book?

London: Singer Zayn Malik is reportedly planning an autobiography, which will lift the lid on his five years in One Direction alongside bandmates Liam Payne, Niall Horan, Harry Styles and Louis Tomlinson. "This book is going to be explosive and Simon Cowell will be furious with Zayn and may even try to stop it from 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," a source Malik is also expected to discuss his high-profile romances, including his broken engagement with Little Mix star Perrie Edwards and his current relationship with supermodel Gigi Hadid. He previously slammed One Direction's music insisting it "wasn't me". Cowell was furious with Malik and said his comments were disrespectful to the group and those who worked with them.
