The R&B star is working on My Prerogative with co-writer Nick Chiles for publishers at Dey Street Books, who promise the "raw and unvarnished" memoir will "tell the full story of his life and set the record straight, particularly about his relationship with Whitney Houston".
Bobby and Whitney wed in 1992 and their tumultuous 15-year marriage was marred by drug abuse, domestic violence and rumours of infidelity.
They had a daughter Bobbi Kristina, who died in July (15), aged 22, after spending months in a coma following a near-drowning in a bathtub at her Georgia home in January (15).
Bobby does not reveal if he will detail the loss of his daughter in the book, but he admits the writing process helped him through the difficult time.
"Right after I signed on to write my story, I went through one of the most agonising traumas I had ever experienced with the death of my daughter," he said. "But I was surprised by how therapeutic it was to work on this project, to look at the entire arc of my life and to realise that although there has been considerable pain, I have also been incredibly blessed.
"I hope my fans and other readers of this book will be entertained by this trip into the crazy, exciting, fascinating world of Bobby Brown. And I hope they will feel that I have been as honest and open with them in these pages as I have tried to be my entire life."
The memoir is due for release in June (16).
Houston died in 2012, aged 48.
