Harry Styles, Zayn Malik, Louis Tomlinson, Liam Payne and Niall Horan have signed a two-book-deal deal with HarperCollins and are planning a tell-all-tale with their autobiography and will also release One Direction: The Official Annual 2015 in time for Christmas later this year. 

Publishing Director Natalie Jones said: ''[It will bring fans] even closer to the band by telling their story in the kind of depth we've not seen before.''

The Story Of My Life hitmakers will release their as-yet untitled autobiography as they embark on their global Where We Are stadium tour, which begins this year.

Natalie added: ''It's a hugely exciting departure from the books we've published with the lads so far.''

The What Makes You Beautiful singers have already released four books, One Direction: Forever Young, One Direction: The Official Annual 2012, Dare to Dream: Life as One Direction and One Direction: Where We Are: Our Band, Our Story: 100% Official, since shooting to fame on talent show The X Factor in 2010.
