Whitney Houston's daughter has been moved to a different medical facility.

Bobbi Kristina Brown, who is ''fighting for her life'' after being found unresponsive in a bathtub at her home in Atlanta, Georgia on Saturday (31.01.15), was reportedly moved from the North Fulton Hospital in Roswell to the Emory University Hospital on Monday (02.02.15).

The 21-year-old aspiring singer, who was placed in a medically-induced coma after being found with ''no heartbeat,'' is said to have ''opened and closed'' her eyes a few times on Monday, but a source close to the family said she remains on a ventilator in the intensive care unit and doctors have warned that they won't be able to tell if she has suffered brain damage until the sedatives can be reduced.

The insider told CNN that she experienced some seizures on Monday and her medical team have decided to keep her in the coma for the time being.

Meanwhile, Kevin Costner, who starred alongside Whitney in 'The Bodyguard' in 1992, admits he ''can't imagine'' what her family is going through.

He told PEOPLE.com: ''That family's under a lot of stress right now, just an enormous amount of stress. I really hope she's okay.''

The 60-year-old 'Black or White' actor, who spoke at Whitney's funeral in 2012 after she was accidentally drowned in a bathtub in a Beverly Hills hotel due to ''effects of atherosclerotic heart disease and cocaine use'', also recently told CBS News that he tried to help the late singer get off drugs.

He said: ''There was two or three times when I was asked to write her letters, that maybe this would have a level of impact on her. I wrote those letters. I never heard back. I was told that she got them. But she went away.''
