London: Cissy Houston is terrified that her granddaughter, Bobbi Kristina, will go down the same path as her mother, Whitney, and die young from drugs.
Last week, it was reported that the Houston family were going to court in a bid to keep Bobbi``s inheritance money protected from bad influences.
And now TMZ claims that sources close to Cissy say the 79-year-old fears Bobbi``s own boyfriend Nick Gordon and father Bobby Brown are capable of ``draining Bobbi``s fortune given half the chance``.
Insiders claim Grammy-winner Cissy wants the 19-year-old to ``mature`` before getting her hands on an estate of 20million dollars.
The trustees of the estate, which includes Cissy, have filed legal documents requesting that the payment schedule to Bobbi Kristina be changed.
