Bobbi Kristina Brown, the daughter of singers Whitney Houston and Bobby Brown, is on a ventilator after an apparent drug overdose, according to multiple media outlets.

Reports say the daughter or the late Houston was only breathing with the help of the machine on Sunday after she was found unresponsive on Saturday at about 10:25 a.m. 

On Saturday morning, Roswell, Ga., police responded to a 911 call and arrived at Bobbi Kristina's home.

Officer Lisa Holland said in a statement that responding officers immediately used life-saving measures.

"Her husband and a friend located her in a bathtub this morning and she was unresponsive. He started CPR and a police officer took over life-saving measures until an ambulance arrived. She was transported to the hospital. Please keep her and the family in your thoughts and prayers."

Brown, 21, was alive when taken to North Fulton Hospital, where she has since been stabilized.

Local police are reportedly sweeping the house for drugs after having secured a search warrant.

"We are interviewing all the family members and friends that were at the house at the time," Holland confirmed at a press conference. "We don't know that if it was an accident or what this could be."

Brown's mother, Houston, died of accidental drowning on Feb. 11, 2012.  Heart disease and the use of cocaine were also listed in the coroner’s report.

Brown's incident comes two weeks after Lifetime aired the Angela Bassett-directed biopic, “Whitney.”

Last year, Brown launched a vitriolic, obscenity-laced Twitter rant against Angela Bassett, who had decided not to include her in the movie. Brown later apologized for the rant.

Bobby Brown, who was not in Atlanta at the time, immediately flew to his daughter’s bedside.
