Bobbi Kristina Brown slams grandmother Cissy Houston’s book ‘Remembering Whitney’

Bobbi Kristina Brown has slammed her grandmother's new book on her pop star mother Whitney Houston, "Remembering Whitney," calling it disrespectful.

Whitney Houston drowned while under the influence of drugs in a hotel bathtub last February at age 48.

Cissy Houston, a Gospel singer, is promoting her memoir in which, according to the Huffington Post, she details her relationship with daughter Whitney, including her battles with drug and alcohol addictions. 

The book also includes details on rumors of a gay relationship and Houston's problems with ex-husband Bobby Brown.

"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, 19, tweeted.

Nick Gordon, Whitney's informally adopted son, is now in a relationship with Bobbi Kristina.

The LA Times cited its own Gerrick Kennedy as writing in a review of "Remembering Whitney": 

"This is a book about a mother grappling with the loss of her child, still wondering if it could have been avoided had her daughter walked away from the pressures of fame or, more heartbreakingly, if she could have averted the disaster."

Bobbi Kristina and her grandmother fought over a $20 million inheritance that was going to the teen, the HuffPost wrote, with Cissy Houston and daughter-in-law, Pat Houston seeking to revise it, believing Bobbi Kristina to be "a highly visible target for those who would exert undue influence over her inheritance and/or seek to benefit from respondent's resources and celebrity."
