Bobbi Kristina Brown's aunt will make sure she didn't ''suffer in vain''.

The 22-year-old aspiring actress - and daughter of the late Whitney Houston - is currently being cared for in a hospice after she was found face down and unresponsive in a bathtub on January 31 and Leolah Brown has insisted the family are doing everything to make sure ''justice is served''.

In a Facebook post, she wrote: ''I hope you all are doing well and are in great spirits! Like always I THANK YOU ALL for your continued prayers and wishes! I have been away simply because I have been with my niece Bobbi Kristina. I am so full right now and won't say much simply because it just ain't time yet!

''But I want you all to know that JUSTICE will be served!!! And I can smile as I say it. If you don't trust anything else in this world-know and understand that I will do all that is in MY power to see to it that my niece Bobbi Kristina Brown is served her justice and did not suffer like this in vain! You have my word! (sic)''

Whilst Leolah didn't make any specific comments, it is thought she is referring to the current lawsuit filed against Bobbi Kristina's boyfriend Nick Gordon, who has been accused of knocking her teeth out.
