Nearing the anniversary of music icon Whitney Houston’s sudden death, Oprah sits down with the singer’s mother, Cissy Houston, in her New Jersey home for her first in-depth, sit-down interview since her daughter’s passing. The superstar’s mother talks about raising a daughter whose voice became a national treasure, teaching Whitney about the music business and her biggest regrets. Oprah also talks to Cissy about when and what she knew about Whitney’s drug use, how she really felt about her daughter’s marriage to R&B singer Bobby Brown and the true nature of Whitney’s relationship with her high school best friend, Robyn Crawford. Later, for the first time since Whitney’s death, Oprah talks to her older brother, Michael Houston (included in photo above). In an emotional discussion, Michael reveals the origin of Whitney’s drug use.
