(NBC NEWS) -- Whitney Houston's brother made a shocking claim when he said he was the first person to introduce the singer to drugs in the 1980's.
Whitney's brother Michael made the admission during an interview with Oprah Winfrey.
However, Houston's mother Cissy still thinks the singer's former husband, Bobby Brown, is to blame for Whitney's drug addiction.
Cissy Houston believes her daughter, Whitney, would have not ended up a drug addict had it not been for Bobby Brown. Houston writes in her book, "Remembering Whitney," her daughter was with someone who wanted to party and Brown never helped Whitney in the way she needed.
Houston writes about a visit to their Atlanta home in 2005 when the walls and doors were spray-painted with "big glaring eyes and strange faces." She says Whitney's face had been cut out of a family picture. Houston says when her daughter and Brown divorced, she was "thanking God so much I'm sure nobody else could get a prayer in to Him."
