Bobbi Kristina's Aunt Leolah Brown Reveals Who Killed Whitney Houston's Daughter

Bobbi Kristina's aunt, Leolah Brown says she's planning on revealing what killed her 22-year-old niece after staying in a coma for months.

She posted on Facebook page, "Please get prepared for the truth to be revealed! I am hurting so badly right now for the death of my niece Bobbi Kristina and what REALLY happened to her! Hold on to your seats as I expose some really terrible things! And please! Most of all...always know that I would NEVER lie on anyone! There's nothing for me to gain that way. Furthermore, it's just not me! I will always speak the truth no matter whom or what!!! Sadly, I feel like I am out here alone fighting for Bobbi Kriss & Whitney! But of course NEVER!!! There is a very powerful Man and Force that I KNOW is with me TRUST!"

Last month, Leolah explained why she skipped out of her deceased niece's funeral and explain that she was tired of people using her and abusing her celebrity, and suggested that she had some incriminating facts regarding her death.

After leaving Bobbi's funeral service early, she told reporters she was outraged at how the funeral was handled and the Sweet 16 party themed funeral the decided to have for her, "I have information! I have evidence! It's not over! It's not over!" she told cameras, "I'll be doing interviews and I'll be speaking out."

Leolah says people around the 21-year-old are to blame for her death, "Krissy was surrounded by people that cared about nothing for her. They didn't care about her just like they didn't care about Whitney."

In 2012, shortly after the singer's death, she foreshadowed Kristina's demise to Access Hollywood, "I am concerned about my niece Bobbi Kristina, yes," Leolah said, "Krissy is not safe right now. I want to say to Krissy that it's very, very, very important that she does not trust anybody at this time. Anybody except her father, her grandmother Cissy and myself. And I mean that. Right now is the time to just really shut the door."
