Bobbi Kristina Brown
Bobbi Kristina Brown remains in a medically induced coma.

Despite moving Bobbi Kristina to an undisclosed rehab facility in Atlanta, doctors have seen "no improvement" in Whitney Houston's daughter condition, Radar Online reports.

Brown has been on a medically-induced coma since she was found face down in a bath at her Georgia home on 31 January. Her boyfriend Nick Gordon is believed to have been first on the scene and administered CPR until the ambulance arrived.

"There is no improvement in Bobbi Kristina's health," a source close to the situation told Radar. "She was moved from the hospital to the rehab place because of hospital policy."

The insider adds that while her father Bobby Brown is optimistic that he will make a full recovery, "the whole family is really hoping for a miracle but it is bleak."

The 22-year-old aspiring actresses' family are now reportedly embroiled in a feud about whether to take her off life support. The Inquistr previously reported that Bobby is locking horns with Cissy Houston and Pat Houston, who believe she is gone and want to remove her from the machines.

"This hasn't gotten any easier for him... It has gotten harder. He really thought she'd be better by now, that there would be some change. There hasn't been any sign of improvement since this happened," a source told the Inquisitr.

In February a family friend revealed that she had suffered seizures when doctors attempted to revive her from her comatose state describing it as a "horrible setback"

"Everyone was hopeful that this was the sign that she'd turned the corner. We were so optimistic," the insider said at the time.
