So much for not kissing and telling. In his upcoming autobiography Bobby Brown: The Truth, the Whole Truth and Nothing But, the performer writes all about his relationship with superstar Whitney Houston and doesn't pull any punches, implying that his ex-wife drove him to use drugs. "I never used cocaine until after I met Whitney. Before then, I had experimented with other drugs, but marijuana was my drug of choice," writes Bobby. "At one point in my life, I used drugs uncontrollably. I was using everything I could get my hands on, from cocaine to heroin, weed and cooked cocaine." He alleges that Whitney married him to save her public image. "I believe her agenda was to clean up her image, while mine was to be loved and have children... The media was accusing her of having a bisexual relationship with her assistant, Robin Crawford," reveals Bobby. "Since she was the American Sweetheart and all, that didn't go too well with her image... In Whitney's situation, the only solution was to get married and have kids. That would kill all speculation, whether it was true or not." For her part, Whitney has denied the rumors in the past. However, Bobby admits to his own faults, too. "I am guilty of sleeping with other women." The sure-to-be-juicy tome comes out next month.
