WHITNEY'S FAMILY BLASTS MOM OVER TELL-ALL BIO

Whitney Houston's relatives have united to battle a seamy tell-all by her own mother!  A source close to the family tells TMZ that it looks like singer Cissy Houston is looking to pocket some cash and salvage her own reputation in the process, saying, "She will try to come out looking like the world's greatest mom, when in reality she wasn't."

Whitney's entire estate is to be inherited by her daughter, Bobbi Kristina.
