Whitney Houston's mother visits Bobbi in hospital

Singer Whitney Houston's mother has visited her granddaughter Bobbi Kristina Brown, who is on life support since last week after being found unconscious in a bathtub at her home in Georgia.
Cissy Houston arrived at Emory University Hospital on Friday afternoon. She was accompanied by several other people, reported People magazine.
An observer said they looked composed and formally dressed. Cissy, 81, has joined her former son-in-law, Bobby Brown, and other family members who have gathered in the intensive care unit.
Bobbi remains unresponsive and can breathe only with the aid of a ventilator.
