Bobbi Kristina Brown, daughter of late US singer Whitney Houston, is in hospital in an unknown condition after being found unresponsive in a bathtub.
Medical privacy laws mean information is restricted, but unconfirmed reports said she was in a medically induced coma to reduce swelling on the brain.
Ms Brown, 21, was found on Saturday by her husband and a friend.
The incident happened less than two weeks before the third anniversary of Whitney Houston’s death.
The singer was found dead in February 2012, aged 48, in a bath in a hotel in Los Angeles.
A post-mortem examination later concluded she died of accidental drowning due to the effects of cocaine use and heart disease.
Medical privacy laws mean there is scant information about Ms Brown’s condition.
‘Ms Brown was found in the bathtub on Saturday morning, Roswell police spokeswoman Lisa Holland has said.
She said that Ms Brown was now at North Fulton Hospital in Roswell, Georgia, and that she was “still alive and breathing”.
At a later news conference, Ms Holland said she could not comment on Ms Brown’s condition because of medical privacy laws.
The police spokeswoman also noted the incident’s similarity with the circumstances of Ms Brown’s mother’s death.
But the 21-year-old’s cousin, Jerod Brown told Sky News: “She’s pretty good right now, she’s around family.
“We’re just praying for a speedy recovery, that’s it… I’m pretty sure she’ll be getting out of there very soon.”
Mr Brown refused to comment on reports that his cousin was in a coma.
Whitney Houston was seen as the golden girl of the music industry in the 1980s and 90s, becoming one of the world’s best-selling artists and the most successful soul singer of all time.
But the hits stopped in the mid-1990s after she began to abuse cocaine, marijuana and prescription drugs.
Bobbi Kristina was born after the singer’s tumultuous 1992 marriage to hip-hop singer Bobby Brown.
The marriage became a public spectacle and ended in divorce in 2007.
