Bobbi Kristina Brown has been taken off life support.

The 22-year-old aspiring actress was placed in a medically-induced coma in January after she was found unresponsive in her bathtub - but her aunt Tina Brown says she is finally getting better.

She posted on Facebook: ''[Bobbi] woke up and is no longer on life support!!!!!:):)God is good!!thanks for your prayers,,still a process,but she is going to be ok:):):):).(sic)''

Tina's social media comments come after Bobbi's father Bobby Brown appeared to suggest she was out of her coma when he came on stage as a special guest at a Maze featuring Frankie Beverly concert at the Verizon Theatre in Dallas on Saturday (18.0.4.15).

It was previously claimed Bobby had disagreed with his late ex-wife Whitney Houston's family over whether to turn off Bobbi's life support machine, with Bobbi's aunt, Pat and her grandmother, Cissy, claiming it isn't ''the best option''.

A source previously said: ''Of course Bobby wants Krissy to wake up and return to her life. That's all he wants. But there doesn't seem to be a lot of hope and the Houston family is resigned to the fact that keeping Krissy on life support may not be the best option.''

Cissy has also said the family are still praying for ''a miracle''.

When asked about Bobbi's condition, she explained: ''She's the same. We've moved her to a place for rehabilitation. And you know, still not a great deal of hope. [We're] still praying.

''I give it to God one time, because I know he's able. And I cannot change a thing. I'm asking everybody: 'Just pray to the Lord who we know can do something about it.' If he works a miracle, thank God. If it happens the other way, I'm alright.''
