Whitney Houston's on/off boyfriend Ray J is to reveal all about his brief romance with socialite Kim Kardashian in a new book.

The singer and reality TV star will reportedly open up about his one-time sex tape partner in "Death of the Cheating Man".

Co-author Maxwell Billieon tells Life & Style magazine Ray J just wanted to "tell the truth" - and he insists there are extracts that will shock and surprise fans, including his ex's lingerie fashion shows and her 'how-to-win-a-man' manual.

The star admits he and Kardashian split after she became too possessive.

He writes, "She wanted to know where I was at all times. She literally thought I was cheating with every girl I ran across."

The details of the new book could not have come at a worse time for Kardashian, who is currently in the middle of a divorce battle with her husband of 72 days, Kris Humphries.
