LOS ANGELES (AFP, REUTERS) - The daughter of the late singer Whitney Houston was pulled unconscious from her bathtub on Saturday at her Georgia home, in an eerie echo of her mother's tragic death three years ago.
Bobbi Kristina Brown, 21, was found by her husband and a friend at her home in Roswell, a suburb north of Atlanta, Roswell Police Department spokesman Lisa Holland said.
Brown's husband, Nick Gordon, started CPR and the police continued life-saving measures until an ambulance arrived and took her to North Fulton Hospital in Roswell.
"She is still alive and breathing and other than that I do not know her condition at this time," Holland told a news conference. "Investigators are on the scene at the hospital and the house."
Entertainment news website TMZ.com reported that sources close to the family said Brown had been placed in a medically induced coma to address swelling on the brain.
The incident comes nearly three years after Houston, a superstar who battled substance abuse, drowned in a bathtub in Beverly Hills, California, in February 2012. The authorities determined that cocaine use and heart disease contributed to her death.
Brown married Gordon in January 2014. He was also raised for a time by Houston, one of the best-selling recording artists of all time, but she never formally adopted him. On her birthday last year, he had his arm tattooed with a portrait of the late singer.
Brown's father, Bobby Brown, is a Grammy winner who started his career as frontman for R&B group New Edition. Both of Bobbi Kristina's parents struggled with substance abuse, and Houston described their 15-year marriage, which ended in 2007, as drug- and alcohol-fuelled.
Bobby Brown was sentenced to 55 days in jail in 2013 after admitting to driving drunk in 2012.
Bobbi Kristina Brown and her grandmother, Cissy Houston, and other relatives starred in a 14-episode reality show for cable channel Lifetime, The Houstons: On Our Own, about their struggle to cope after Houston's death.
Brown's Twitter feed over the past year included motivations to work out, quotes from celebrities on being true to oneself, loving messages for her husband and remembrances of her mother.
