One Direction are set to release two new books.
The 'Story of My Life' hitmakers are planning to reveal all to their fans in a new autobiography as well as releasing 'One Direction: The Official Annual 2015', both of which will be published by HarperCollins.
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 boy band - Harry Styles, Zayn Malik, Louis Tomlinson, Liam Payne and Niall Horan - will release their as-yet untitled autobiography as they embark on their global 'Where We Are' stadium tour, which begins this year, and fans will be able to purchase the hardback book for £20.
The group's 2015 annual will be packed full of exclusive photos and behind-the-scenes stories and be in stores in time for Christmas priced at £7.99.
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.
Fans of the band - nicknamed Directioners - will no doubt be keeping their fingers crossed that the latest autobiography will lift the lid on the hunks' relationships, including Harry Styles' rumoured romance with 'Keeping up with the Kardashians' star Kendall Jenner, and Zayn Malik's engagement to 'Little Mix' singer Perrie Edwards.
