A number of publications confirmed that pictures from the 22-year-old's hospice bedroom in Atlanta had been doing the rounds, and were being sold for upwards of USD 100,000, reported Billboard.
It is believed that Bobbi Kristina's family have been letting in relative and close friends to "say goodbye" to her, and the pictures were being touted by "an extended family member".
Leolah took to Facebook to rage against the unknown culprit.
Bobbi Kristina has been unresponsive and in a coma ever since she was hospitalised on January 31 this year, having been discovered unconscious in her bathroom at home.
Doctors believe that she would now require a miracle for her to ever recover, and last month her co-guardians - Bobby Brown, her father, and Pat Houston, her aunt - took the decision to move her to a hospice.
