Bobbi Kristina sparks concern

Whitney Houston's daughter Bobbi Kristina has once again sparked concern for her own wellbeing after allegedly posting a photo to Instagram in which she is smoking what appears to be a marijuana bong.

The 21-year-old accompanied the image with a rambling message about it being an old photo but that she posted it in attempt to 'make a connection' with her fans - though she has since taken to Twitter to deny she ever posted it and changed her account settings to private.

The photo in question shows the recently married star clad in grey tracksuit pants and a white singlet top as she leans over a long clear glass pipe that is filled up with smoke.

She has the pipe to her mouth as she inhales what is presumed to be marijuana.

'This picture may be inappropriate but I want to make a connection with you all,' she apparently wrote in explanation of the troubling shot. '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,' she continued. '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 (sic).

'People kinda expect more from me. But I can't. I have lost my sense. It just happened. Then here we go again I'm in the same pain. I'm hurt. I'm trying to. I really do. But I know that I'm hurt and in pain but I can feel it but I don't know what it is (sic).'

She concluded: 'What do I really do? God, Help me ignore and rebuke what these demons are saying, in Jesus Name. Amen (sic).'

While it's not known what 'situation' she is specifically referring to that is causing her so much pain, it's clear that she's struggling with some very deep-seated issues in her young life.

Of course, having lost her beloved mother little more than two years ago, it's likely that's still weighing heavily on her mind.

She also had a rather public falling out with her extended family members, who disapproved of her relationship with her pseudo brother, Nick Gordon, whom she went on to marry in early January.

Bobbi Kristina's latest rant comes just weeks after she slammed Angela Bassett for not casting her as her late, great mother in the upcoming biopic Whitney And Bobby - a role that went to former America's Next Top Model contestant and actress YaYa DaCosta.
