The aunt of Bobbi Kristina Brown vows whoever took the photos of her ailing niece in her hospital bed and is now offering to peddle them to the highest bidder will be exposed.

According to People magazine, Leolah Brown angrily took to Facebook over the July 4 holiday weekend to warn her family's tormentor after several outlets, including TMZ and Entertainment Weekly, confirmed that they have been contacted.

Sources at ET added the photos were taken from inside Bobbi Kristina's hospice room and the caller was seeking in excess of $100,000 for them.

"You took that picture thinking you gon get some money for it...and thats gon be it," Brown posted to her Facebook page Friday. "Guess what!????!!!! I will myself if no one else does-see to it that -YOU be revealed!!!"

The 22-year-old daughter of Bobby Brown and Whitney Houston has remained unresponsive ever since being found face down in the bathtub of the Georgia home she shared with boyfriend Nick Gordon in late January. Family members recently made the agonizing decision to take her off her life-preserving medications and move her to a hospice where she can "die naturally."

Since she's been hospitalized, police have also launched a criminal probe of the circumstances leading to her injuries after doctors discovered several other unexplained bruises on her body. TMZ previously reported the 25-year-old Gordon is the primary target of that investigation.

More recently, several media outlets have reported Bobbi Kristina is expected to be buried alongside her mother so the two can be together in "eternity."

Whitney Houston died a little more than three years ago after she too was found face down in a bathtub of a Beverly Hills hotel where she was staying. Authorities later revealed she had drugs in her system at the time of her death.
