Bobbi Kristina Brown's health is "not progressing at all"

Asked about the state of her granddaughter's health, Cissy said: "[It's] the same, she's not progressing at all."

However, Cissy insisted she's prepared for whatever happens to Bobbi in the coming weeks and months.

She told 'Entertainment Tonight': "She's not gone yet, but you know, whatever the lord decides, I'm ready for her ... I have nothing to do with that. That's his job. It's his territory, you know? And I understand it."

Cissy also voiced her support for the recent decision to make Bobbi Kristina's father Bobby Brown and aunt Pat Houston her co-guardians, thereby placing them in charge of her medical and care needs.

Of the decision, she said: "It was fine. We're a family ... that works together for the best. You want the best for whomever or everybody we can."

Last month, Cissy - the mother of the young star's late mother Whitney Houston - said Bobbi has suffered "irreversible brain damage".

She explained: "I have just returned from visiting my granddaughter Bobbi Kristina in the hospital and while she is no longer in a medically induced coma she has a tracheotomy and according to the doctors she has global and irreversible brain damage and remains unresponsive."
