Bobbi Kristina Brown's aunt claims legal co-guardian Pat Houston recently told Bobby Brown it was "costing too much money" to keep the only daughter he shared with Whitney Houston alive.

According to Us Weekly, Leolah Brown took to her Faceboo account on Tuesday to discuss Bobbi Kristina. The post was later deleted.

"The big lie has been told again that my niece Bobbi Kristina is going to be brought home...only to leave us," Leolah said. "Bobbi Kristina Brown is 'not' on life support anymore ... And we will never give up onher! Hell no! Not one Brown!"

The website added Leolah insists her 22-year-old niece is getting the best care possible and continues to show signs of improvement. Much of her anger was reserved for Pat, who along with Bobbi Kristina's father was named as her co-guardian by an Atlanta judge late last month.

"Ms. So-called Pat Houston... had the nerve to sarcastically say to my brother Bobby, 'why don't he just pull the plug on Bobbi Kriss, because it's costing too much money to keep her alive!'" Us Weekly claimed Leolah charged. "Yes, Pat Garland did have that nerve to say that to Bobbi Kristina's father Bobby."

While Cissy Houston has previously declared that doctors have informed the family that the brain damage suffered by Bobbi Kristina is irreversible, Us Weekly reported Leolah had total confidence in God.

"God is on our side," she said. "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."

Leolah went on to charge that Whitney disliked Pat. Therefore, Leolah believes that if Whitney were still alive, she would not allow Pat near her daughter. She believes Pat is motivated by the $20 million estate Whitney left to her daughter in her will.

Bobbi Kristina has remained unresponsive since being found face down in the bathtub of the Roswell home she shared with boyfriend Nick Gordon.

TMZ has previously reported authorities have now launched a criminal investigation surrounding the circumstances of her injuries after doctors discovered several other unexplained injuries on her body. Reportedly, the probe targets Gordon as the primary suspect.
