That's the most shocking reveal to come from the first day of Oprah's two-part interview with the drugged-out diva.
Houston said during the interview that Bobby Brown wasn't physically abusive during their tumultuous marriage but that he was emotionally abusive.
"He slapped me once but he got hit on the head three times by me," Houston said. But that wasn't the worst incident, as far as she was concerned.
The 46-year-old singer says she "was horrified he spit on me, in my face" and that left her "very hurt, very angry."
Houston also said she took drugs with ex-husband Bobby Brown, including cocaine and marijuana. She called Brown her "drug," saying she stayed with the pop star because of a pseudo-addiction to the relationship.
Houston says she was attracted to Brown because he had control in their relationship. Houston and Brown married in 1992 and were divorced in April 2007, but things got so bad between the two that Houston says at one point she stopped thinking about singing.
After a long absence from music, Houston is staging a career comeback with a new album last month and a two-part appearance on "The Oprah Winfrey Show." Houston told Winfrey that Brown would smash and break things in their home. She said after a birthday party for Brown she was horrified because he spit on her. She also described her drug abuse, saying it became "heavy" after her 1992 movie "The Bodyguard."
Houston is one of the best-selling artists of all time, but her career stalled as she grappled with drug problems and a troubled marriage to Brown.
