Bobbi Kristina Brown: Leolah Brown slams 'money-grabbing' Pat Houston in angry Facebook rant

The Brown-Houston family feud continues, as Bobby Brown's sister claims that Pat Houston wants Bobbi Kristina Brown to die so that she can inherit the late singer's estate.

Leolah Brown posted an angry Facebook rant in which she alleges that Whitney Houston's sister-in-law is motivated entirely by greed and is not concerned with Bobbi Kristina's well-being.

Pat Houston was Whitney's manager and the wife of her brother Gary. She was recently named co-guardian of Bobbi Kristina's estate, along with the 22-year-old's father Bobby Brown.

Bobbi Kristina is the sole heir of her mother's estate, which is estimated to be worth $20 million (£12.63m). If Bobbi Kristina were to die, Pat stands to inherit the fortune.

In the scathing Facebook message posted on 16 June Leolah Brown wrote: "If Pat knew The God that I know, instead of trying to inherit my niece's money for her personal gain, she would mind her own business and go find A JOB for herself without continuously working so hard to destroy my niece, beg her for money and get angry when she cannot get it!. She would stop using the Houston name for her personal agenda."

Leolah Brown also denied reports her niece was still on life support. She explained that contrary to reports that doctors have given up all hope for her recovery, Bobbi Kristina's condition is improving.

"Please be sure and know that, ONLY my brother Bobby Brown and my brother Tommy Brown who is Bobbi Kristina's father and uncle, has gotten Bobbi Kristina the best care possible and that she is indeed continuing to improve in-spite of the LIES being told. AND WE THE BROWN'S ARE CONTINUING TO PRAY TO GOD FOR HER RECOVERY."

She added that Pat Houston was not allowed near the 22-year-old, "per Bobbi Kristina's request."

Leolah had earlier expressed her concerns that Bobbi Kristina's life was deliberately endangered adding that she believes Nick Gordon will "110 per cent' be charged with a crime in connection to Bobbi Kristina's injuries.

She told Fox 5 Atlanta. "I saw this coming. I told her not to trust anyone."

Bobbi Kristina was found face down and unresponsive in the bath tub in her Roswell home on 31 January. She was placed in a medically induced coma and has remained on life support ever since. She was transferred to the DeKalb Medical facility in Atlanta, a long-term care facility, as the family have been embroiled in public disputes over her future care and have offered conflicting reports about her condition.

Whitney Houston's mother, Cissy Houston, recently denied the Brown family's claims that Bobbi Kristina was improving. The 81-year-old Houston matriarch said her granddaughter was "not progressing at all" and had suffered 'irreversible brain damage."

In a statement released to People Magazine, Houston said: "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."

Meanwhile, Bobby Brown and his sister Tina were reported to have claimed that Bobbi Kristina was awake and had been taken off life support. The singer also slammed reports that the family were preparing to take his daughter off life support

Don't believe any reports that Bobby is going to take her off life support," a family source told People magazine. "He's never going to do that. I don't think he'll ever go there; if there's a 2% chance, a 1% chance, a 0.1% chance, he will keep hope alive."

The incident, which, has been classified as a criminal investigation, happened before the third anniversary of her mother Whitney Houston's death, who died on 11 February 2012 in similar circumstances.
