I never posted bong shot online: Bobbi Kristina Brown

Los Angeles: Whitney Houston`s daughter Bobbi Kristina Brown has assured fans that a photo of herself getting high, which was posted online, is a hoax.

Earlier this week, the snap of Brown, 21, smoking what appeared to be a bong was shared on Instagram but the reality TV star insists reports she uploaded it are not true, reportedly.

The picture was captioned, "This picture may be inappropriate but I want to make a connection with you all. Don`t worry this picture isn`t recent just hear me out. Do you know what I feel? I feel strange I can`t feel any pain anymore. I don`t take any drugs as of recently.

"Things just happened. But then there is some situation that force me to do things and the impact I`ll feel pain. I did and I do. I was hurt."

The Instagram account has since been deleted and now Brown states, "I`ve never posted any photo of me doing anything! This is someone trying to tarnish and make a horrible name for Myself. People are insane."

Houston battled substance abuse throughout her life and cocaine was listed as a contributing factor in her death in February, 2012, when she drowned in a bathtub.
