Bobbi Kristina Brown is ''still fighting the battle of her life.''

The 22-year-old beauty's auntie Patricia Houston updated fans on the youngster's condition last night (04.03.15) as she remains on life support at Emory University Hospital in Atlanta.

Taking to the late Whitney Houston's official website, Patricia wrote: ''Today is Bobbi Kristina's 22nd birthday and we ask you to continue to keep her in your prayers as she is still fighting the battle of her life. Patricia Houston, President.''

It is also believed the aspiring actress' father Bobby Brown organised a special bedside vigil to mark her annual milestone and invited several members of her extended family to join him at the medical centre as her marked the occasion.

Meanwhile, doctors attempted to bring Bobbi Kristina out of a medically-induced coma last week, but were forced to abandon their efforts after she reportedly started having seizures.

A source close to the family previously admitted: ''This is a horrible setback. Everyone was hopeful that this was the sign that she'd turned the corner. We were so optimistic.''

The daughter of the late Whitney was rushed to hospital on January 31 after she was found unresponsive in a bathtub at her home in Atlanta by her boyfriend Nick Gordon.

The hunk has reportedly been banned from seeing his girlfriend at the hospital and has lashed out her family for blocking him.

He tweeted recently: ''My heart is full of angry after the Browns have shut me out. They don't even know her. Sabotage.

''I miss her so much. I seem so weak right now. You all have been so supportive! Thank you for everything.''
