Whitney Houston "forgot" she was a singer during the depths of her drug addiction.

The music star admitted the extent of her substance abuse and the lowest points of her 14-year marriage to singer Bobby Brown during an emotional interview with Oprah Winfrey which aired in the US yesterday (14.09.09).

Referring to her crack cocaine and marijuana use, Whitney, 46, said: "I didn't think about the singing part anymore. I'd totally forgotten about that life. I had so much money by that time."

She went on to detail how she and Bobby, 40, would 'freebase' crack in marijuana joints, adding: "We were lacing our marijuana with base. We would buy a kilo. We were not pipe smoking.

"You roll it up and you smoke it in your weed. It's almost like heroin cocaine speedballs but you level it off with marijuana."

Whitney - who separated from Bobby in 2006 and divorced him a year later - claimed her ex-spouse became jealous of her career after she appeared in the worldwide hit 1992 film 'The Bodyguard' - after which their drug abuse spiralled out of control.

She said: "I think somewhere inside, something happens to a man when a woman has that much control or has that much fame.

"Emotionally he was abusive. Physically, no way. I was raised with two brothers and I would fight you back with anything I could find."

She recalled how Bobby's abuse spilled over one night after she had thrown a birthday party for him.

Whitney - who has a 16-year-old daughter Bobbi Kristina with Bobby -recalled: "When we got back to the house he spit on me. He actually spit on me. And my daughter was coming down the stairs and she saw it.

"I was angry. I was very hurt. I knew something was going to blow. That was pretty intense.

"I didn't grow up with that and I didn't understand why that occurred - why he had such a hate for me because I loved him so much."
