Blue are set to tell-all in a brand new book.
The boy band – comprised of Lee Ryan, Duncan James, Simon Webbe, and Antony Costa – are gearing up to release an autobiography detailing the ups and down of their 16-year career, and have "really enjoyed" having the chance to open up about their lives.
A source told The Sun newspaper: "This book has more highs and lows than ‘Game of Thrones’, and almost as much drama.
"They really enjoyed opening up – they’ve been through some real tough times both individually and as a band."
The book is set to detail the secret battle with depression which left 38-year-old Simon contemplating suicide, whilst Lee, 33, opens up about his throat cancer scare which left him unable to perform for almost 18 months.
And on an excerpt obtained by the publication, Duncan, also 38, uses the book to pay a heartfelt tribute to his late friend and socialite Tara Palmer-Tomkinson.
The ‘One Love’ hitmaker writes: "We   were  like two naughty little school children. I’d never had a friend like her. We definitely brought out the mischievous side in each other. No one was safe!"
It isn’t the first time the star has gushed about the beauty – whom he dated between 2008 and 2009 – as he previously dubbed her as "simply amazing".
Speaking about TPT – who was tragically found dead at her home earlier this month – Duncan said: "She had an energy about her that was simply amazing. I have so many fond memories from all the holidays we shared together, countless nights out in wonderful restaurants. I will treasure all of those moments as some of the best times of my life."
As of the time of writing, no release date for the autobiography has yet been announced.
