Oprah gives viewers a sneak preview of her sit-down interview with Whitney Houston’s family; her daughter, Bobbi Kristina; her brother, Gary Houston; and her sister-in-law, Patricia Houston. The special episode of “Oprah’s Next Chapter” airs on Oprah’s struggling OWN Network next Sunday at 9/8c.

Bobbi Kristina shares personal memories of her mom and how she would like the iconic superstar to be remembered.

Although Oprah’s TV special gives the impression that Whitney’s surviving daughter, Bobbi, is doing well, the current issue of the National Enquirer (on newsstands now) tells a different story. The March 12, 2012 cover features new photos of Bobbi Kristina smoking a big bowl of weed through a bong. It’s doubtful that Oprah asked if Bobbi Kristina was going to a drug rehab anytime soon.
