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.
