Los Angeles, Feb 3 (IANS): Bobbi Kristina Brown's family has broken its silence to confirm that late singer Whitney Houston's daughter is still “fighting for her life".

The 21-year-old was found face down in a bath tub at her home by her husband Nick Gordon and a friend last week.

A statement from the family read: “Bobbi Kristina is fighting for her life and is surrounded by immediate family. As her father already stated, we are asking you to honour our request for privacy during this difficult time.

"Thank you for your prayers, well wishes, and we greatly appreciate your continued support.”

According to various sources, the swelling on Bobbi's brain has been reduced and she has been able to “move her eyes” as oxygen levels have increased significantly, reports mirror.co.uk.

The doctors have recorded four times more oxygen in her brain than they did Sunday.

However, they fear she may have suffered neurological damage after being under water for between two and five minutes.
