Bobbi Kristina Brown, the daughter of the late singer Whitney Houston, was found unresponsive in a bathtub in her Georgia home Saturday, police said. Brown's husband, Nick Gordon, and a friend found her in the tub in the morning and started CPR, the Roswell Police Department said in a statement. Police and rescue personnel arrived at the home, north of Atlanta, at 10:25 a.m. and performed "life-saving measures" before Brown, 21, was brought breathing to the nearby North Fulton Hospital.

The incident remains under investigation, police said. It comes less than two weeks before the third anniversary of Houston's death. The Grammy-winning singer was found submerged in a bathtub in a Beverly Hills, California, hotel on Feb. 11, 2012. She was later pronounced dead. Brown is also the daughter of R&B singer Bobby Brown.

Houston, 48, had struggled for years with cocaine, marijuana and pills, and her behavior had become erratic. Authorities examining Houston's death found a dozen prescription drug bottles in the hotel suite. They concluded that she accidentally drowned. Heart disease and cocaine use were also listed as contributing factors in her death.

Earlier this month, Lifetime released the biopic, "Whitney," which focused on the "I Will Always Love You" singer's drug use. Houston's sister-in-law, Pat Houston, released a statement blasting the film and said neither her mother, Cissy Houston, or Bobbi Kristina Brown, were consulted.
