Whitney Houston's only child, Bobbi Kristina Brown, is reportedly brain dead following an apparent suicide attempt at her Roswell home early Saturday, according to a source.
Brown, 21, was found submerged face down in a bathtub filled with water at her townhouse in the Ellard Subdivision just north of Atlanta.
Brown was unresponsive when she was pulled from the tub by her estranged husband Nick Gordon and a friend, who began CPR until Roswell police arrived at the scene and took over emergency resuscitation efforts.
A source told Sandrarose.com that Brown was not breathing and did not have a heartbeat when she was lifted out of the water.
It is unknown how long Brown was deprived of oxygen, but irreversible brain death normally occurs after 4 minutes.
Brown's doctors are trying to determine if she attempted suicide or if she met with foul play.
Police did not find drugs in the home -- an indication that prescription drugs may have been intentionally removed from the home. Brown had a history of substance abuse.
There are unconfirmed reports that Brown and Gordon fought last week and Gordon moved out of the home to stay with a friend. Brown reportedly called Gordon from the bathroom to say she was going to take her life.
Hiphopenquirer.com reports exclusively that Brown's family (Pat Houston) took out a restraining order preventing Gordon from seeing Brown at North Fulton hospital where Brown is in the intensive care unit.
Brown's distraught father, R&B singer Bobby Brown, 46, arrived at the hospital around 7:30 p.m. Saturday, accompanied by family friend, director/playwright Tyler Perry.
Entertainment Tonight reports that the family will make the decision to release the news of Bobbi Kristina's death to the public after she is taken off life support.
Brown's mother, singer Whitney Houston was pronounced dead at age 48 after she drowned in a bathtub at the Beverly Hilton Hotel on February 11, 2012. The coroner ruled Whitney's death an accidental drowning, but drugs were found in her system.
