In one chapter, Bobby claims that it was Whitney who introduced him to cocaine, and not the other way around as people have long suspected.
"I never used cocaine until after I met Whitney. Before then, I had experimented with other drugs, but marijuana was my drug of choice," wrote Brown, who shares 15-year-old daughter Bobbi Kristina with Houston.
Responding to the allegation, Whitney's rep tells People magazine in a statement: "Miss Houston is sad that Bobby feels he needs to say such things but she chooses to take the high road and will not speak badly about the father of her child even if it's to set the record straight."
