Whitney Houston's daughter found unresponsive in bathtub

Atlanta - Bobbi Kristina Brown, the only daughter of late pop star Whitney Houston and singer Bobby Brown, was found unresponsive in a bathtub at her Georgia home on Saturday, but she was revived after being rushed to a hospital, police said.

The incident comes three years after Houston, a superstar who battled substance abuse issues, drowned in a bathtub in Beverly Hills, California, in February 2012. Authorities said cocaine use and heart disease contributed to her death.

Brown, 21, was found at about 10:20 (15:20 GMT) in the bathtub at her suburban Atlanta home by her husband and a friend, said Lisa Holland, public information officer for the Roswell police department.

Brown's husband, Nick Gordon, started CPR and police continued life-saving measures until an ambulance arrived and took her to the hospital.

"She's alive at the hospital," Holland said. She gave no other details.

Brown was admitted to North Fulton Hospital in Roswell, a suburb north of Atlanta, the Atlanta Journal Constitution reported.

Hospital officials did not immediately respond to calls requesting comment.

Brown married Nick Gordon in January 2014. Gordon was also raised by Houston, one of the best-selling recording artists of all time, but she never formally adopted him.

Houston, whose dozens of hit songs include How Will I Know and I Will Always Love You, was the daughter of gospel singer Cissy Houston and a cousin of pop singer Dionne Warwick.

Bobbi Kristina Brown's father, Bobby Brown, is a Grammy Award winner who started his career as frontman for the R&B group New Edition.
