Whitney Houston's Ex Bobby Brown to Release Memoir, 'Every Little Step'

— -- Bobby Brown was a wildly successful R&B singer who ruled the radio waves, having been the former front man of New Edition and later a Grammy-winning solo career. Whitney Houston remains one of pop music’s best-selling artists of all time and rose to international fame with her show-stopping singing and acting career.

Together they had one of the biggest celebrity marriages.

Now for the first time, Brown will share stories about his life. In the book, "Every Little Step," Brown, 47, writes about his decades-long successful music career and opens up about plans for future steps on the road ahead.

"Writing this book has been a therapeutic process for me," Brown told ABC News. "Getting it all out has allowed me to move on with my life."

Brown will sit down with ABC News’ Robin Roberts for an interview to air in a special edition of ABC News “20/20” on Tuesday, June 7, and discuss at length the truth about his journey.

“Every Little Step” will go on sale in June and is published by Dey Street Books.
