Whitney Houston’s daughter Bobbi Kristina Brown was found unresponsive Saturday morning in a bathtub full of water in Roswell, Georgia, police in that Atlanta suburb said.

Brown “was not breathing” when her husband and a friend found her around 10:25 a.m. at a home in a Roswell subdivision, police spokeswoman Lisa Holland said.

“They called 911, started CPR on her, and police arrived first,” the spokeswoman added. “We took over the lifesaving measures until the fire/rescue and an ambulance arrived.”

Brown was then transported to Roswell’s North Fulton Hospital, where she was breathing, according to Holland.

It was three years ago February 11 that Brown’s mother, renowned signer Whitney Houston, was found dead in a bathtub in The Beverly Hilton, hours before she was to attend a pre-Grammys bash there.

An autopsy later revealed that she’d drowned face down in “extremely hot water” about 12 inches deep. The Los Angeles County coroner ruled it an accidental drowning with the “effects of atherosclerotic heart disease and cocaine use” being contributing factors.

Shortly after her mother’s death, a grieving Bobbi Kristina — then 18 — was taken to Cedars-Sinai Medical Center because she was “overwhelmed,” family friend Kim Burrell said.

“She loves hard,” Burrell said then of Bobbi Kristina. “She’s going to be OK, and we’re going to see to it.”

Months later, Brown reportedly got engaged to Nick Gordon, whom Houston took under her wing as a youngster and raised alongside Bobbi, according to Entertainment Weekly and other reports.
