Whitney Houston's Brother Admits He -- NOT Bobby Brown -- First Introduced Whitney to Crack Cocaine in the '80s

Oprah is becoming the go-to person for celebrities to get things off their chests and she's proven once again she has the inside line to the Houston family. Remember, she was the first person to interview the family after Whitney Houston died last year from accidental drowning after she snorted or smoked crack cocaine. In her latest interview, Oprah talks with Cissy Houston, who has a book coming out Tuesday about Whitney and she brought along one of Whitney's older brothers, Michael Houston, to clear up a major misconception. Michael, who many in the family called Whitney's twin, hasn't spoken publicly -- until now. He tells Oprah he and Whitney were inseparable and he was the first person to introduce her to crack cocaine and other drugs back in the '80s -- long before she met and married Bobby Brown. He says he feels responsible for her death. According to Roger Friedman, Michael was arrested for possession of cocaine, marijuana, drug paraphernalia and being under the influence of drugs in Fort Lee, N.J. in 2001 after a traffic stop. Whitney’s other brother, Gary, was also pulled over by police in Charlotte, North Carolina in 1996 and was arrested for possession of crack cocaine. Reportedly, Whitney's daughter, Bobbi Kristina, is also addicted to crack cocaine. A mess.

Speaking of which: Cissy says she's "heard" that Bobbi Kristina is a drug addict, but she hasn't been able confirm it, because the 19-year-old doesn't return her calls. Um, this lawsuit she filed against Bobbi Kris may have something to do with that. Cissy also adds that she doesn't care much for her famewh*ring daughter in law, Pat Houston, either. We had a bad feeling about her, too.



Cissy also addressed Whitney's long-rumored lesbian relationship with Robyn Crawford.
