Who Was Whitney Houston?

While growing up in New Jersey, Whitney Houston was close to both of her big brothers, Gary and Michael. Since his sister’s death, Michael, who many in the family called Whitney’s twin, hasn’t spoken publicly. Now, Michael reveals how he introduced Whitney to drugs in the ’80s, long before Whitney married Bobby Brown. Watch as he discusses the guilt he lives with every day.

In 2009, Whitney Houston sat down with Oprah to discuss her battle with addiction, her troubled marriage to Bobby Brown and more. In what would be her last interview with Oprah, Whitney recounted the day her mother, Cissy Houston, staged an intervention and got her to go to rehab. Cissy describes that day to Oprah and reveals why it was difficult for her to watch that 2009 interview.

Cissy Houston has a few words, and a few more, for Bobby Brown.

In “Remembering Whitney,” the mother of the late Whitney Houston writes that from the start she had doubted whether Brown was right for her daughter. And she thinks that Whitney might not have ended up so “deep” into drugs had they not stayed together.

“I do believe her life would have turned out differently,” Houston writes. “It would have been easier for her to get sober and stay sober. Instead she was with someone who, like her, wanted to party. To me, he never seemed to be a help to her in the way she needed.”

“Remembering Whitney” was released Tuesday, two weeks short of the first anniversary of Houston’s death. She drowned in a hotel bathtub in Beverly Hills, Calif., at age 48. Authorities said her death was complicated by cocaine use and heart disease, but many still question the facts surrounding the singer’s death.

Houston said she has no contact with Brown and didn’t see any reason to, not even concerning her granddaughter, Bobbi Kristina.

She reaffirmed her comments in the book that Whitney Houston would have been better off without him. “How would you like it if he had anything to do with your daughter?” she asked.

Brown is portrayed as childish and impulsive, hot tempered and jealous of his wife’s success. Cissy Houston describes a 1997 incident when Whitney sustained a “deep cut” on her face while on a yacht with Brown in the Mediterranean.

Whitney insisted it was an accident; Brown had slammed his hand on a table, breaking a plate. A piece of china flew up and hit Whitney, requiring surgery to cover any possible scar. The injury was minor, the effects possibly fateful.

“She seemed sadder after that, like something had been taken away from her,” Houston writes.

Brown and Whitney Houston divorced in 2007, after 15 years of marriage. When she learned that her daughter was leaving Brown, Cissy Houston was “extremely relieved” and “thanking God so much I’m sure nobody else could get a prayer in to Him.”

Cissy Houston writes that sometimes she hears a doorbell ring and thinks it’s Whitney, or sees a vase in a different place and wonders if her daughter is around. Some nights, Cissy Houston wakes up crying, not sure at first where she is.

“But then I get up out of bed, wipe my eyes, wash my face, and lie back down to my sleep. Because that is all I can do,” she writes. “I am so grateful to God for giving me the gift of 48 years with my daughter. And I accept that He knew when it was time to take her.”
