Cissy Houston won't use 'heroic measures' to save granddaughter Bobbi Kristina

The gospel singer, Cissy Houston, who is now sharing the controls with Bobby Brown over her granddaughter, Bobbi Kristina, has strongly indicated that she won't use any heroic measures to save her.

The 22-year-old comatose singer's co-guardian, Pat Houston said that she and Brown were working as a family to make medical decisions, but there was clear division, TMZ.com reported.

The American RandB singer, 46, said that he would do whatever it took to keep his daughter alive, including using heroic measures if she begins to slip away.

Bobbi Kristina, who is suffering from irreversible brain damage, is now the joint responsibility of Brown and Houston as per the judge's statement, which was made few days ago.
