Bobbi Kristina Brown calls grandmother's book 'disrespectful' Singer Whitney Houston (L) and her daughter Bobbi Kristina Brown arrive at the Pre-Grammy Gala & Salute to Industry Icons with Clive Davis honoring David Geffen in Beverly Hills, California on February 12, 2011. LOS ANGELES, Feb. 4 (UPI) -- Bobbi Kristina, the daughter of late U.S. pop star Whitney Houston, says her grandmother's new book is disrespectful and she wants nothing to do with it. Gospel singer Cissy Houston has been on the interview trail to promote her new memoir, "Remembering Whitney," which details her affectionate but sometimes stormy relationship with her daughter, who battled addictions to drugs and alcohol for years. Anything concerning my grandmother's book, I and @nickgordon of course personally have nothing to do with... I haven't read and won't... I find it to be disrespectful to my mother and me being her daughter won't tolerate it," Bobbi Kristina, Whitney Houston's 19-year-old daughter, tweeted Sunday. Nick Gordon is Bobbi Kristina's boyfriend and Whitney's informally adopted son. Whitney Houston accidentally drowned in a hotel bathtub in February 2012 after using drugs. She was 48.
