The 21-year-old actress was discovered in the bathroom of her home in Roswell, Georgia at 10.30am local time, and was rushed to hospital where she is now believed to have been stabilised by doctors.
The star was discovered by her husband Nick Gordon and a friend, who conducted CPR until police and paramedics arrived and took her to the nearby North Fulton hospital in an ambulance.
The incident comes three years after her mother passed away in a bathtub at the Beverly Hilton Hotel in Beverly Hills on February 11 2012.
The Los Angeles County coroner's office later confirmed the 'I Will Always Love You' hitmaker passed away as a result of drowning and "effects of atherosclerotic heart disease and cocaine use".
The cause of Bobbi's incident is currently unknown, but local police are investigating the situation at her home while she recovers in hospital.
