Bobbi Kristina Brown, the daughter of the late vocal icon Whitney Houston, has admitted that she won't be picking up a copy of the book her grandmother wrote about her mother because she doesn't agree with it at all.

79-year-old Cissy Houston (pictured below) has penned a tell-all memoir, entitled 'Remembering Whitney', and she has been promoting it heavily with interviews and magazine coverage. In the book, Cissy reveals that Bobby Brown wasn't a bad influence on her daughter and even claims he didn't introduce her to drugs, but Bobbi Kristina doesn't believe a word of it.

Writing on her official Twitter page over the weekend, Bobbi Kristina slammed the memoir's content and told her 120,000 followers that she doesn't want to be associated with it:

"ANYTHING concerning my grandmother's book, I& @nickdgordon OF COURSE personally have NOTHING 2 do with. I ask you pls RESPECT tht. Haven't read & won't. I find it 2 B Disrespect 2 MY MOTHER, & me being HER DAUGHTER won't tolerate it. I LOVE YOU ALL for your support though & I thank you immensely. xO!"
