Fox411 columnist Roger Freidman spoke with the co-writer of Bobby Brown's upcoming autobiography to get even more information on revelations featured in the May 13th release.

Self-published with distributor Atlas Books of Ohio, "Being Bobby Brown: The Truth, the Whole Truth and Nothing But…" is co-written with Derrick Handspike, an Atlanta hip-hop producer and author of several books, notes Friedman.      

When asked the motive behind dishing dirt on ex-wife Whitney Houston, Handspike answered: "We are very wealthy from this already." Handspike intimated that there are "investors," adding, "It’s a joint-venture kind of thing."      

In addition to chapters about his cocaine use, which were excerpted in New York newspapers last week, Handspike says that Brown has also overdosed on heroin.      

"No one knows that," he told Friedman. "He had a stroke. They said he had a heart attack but he had a stroke."      

In the book, Brown says his heart stopped three times and he had to be revived with shock paddles.      

According to Handspike, Brown also admits to hitting Houston. "He considered it horse play," he said. "The reason Whitney called the police was that he laughed at her and then left. She said, 'You think you’re going to just walk away from this?' Then she called the police."      

Brown's publicists are said to have adopted an aggressive game plan to promote the book.      

"Brown's press reps are approaching all the shows and made an inquiry to Oprah," Friedman wrote in Sunday's column. "The angle is gong to be that this is Brown’s way of telling his story, and that there’s very little about Whitney — at least not enough for which to sue him."
