TMZ sources state that the 18-year-old, the only child of Houston and ex-husband Bobby Brown, was taken from the Beverly Hilton hotel on a stretcher.
Beverly Hills police have reportedly confirmed that Bobbi was transported to Cedars-Sinai Hospital at 10.30am PT.
Meanwhile, a source tells People that Bobbi was first taken to hospital hours after her mother's death "because she was having a complete breakdown".
Previous reports suggested that Bobbi was denied access to her late mother's body, leading to an altercation with police officers outside of the room in which the 48-year-old passed away.
Houston's body was discovered in her room on the fourth floor of the hotel yesterday (February 11). An autopsy is expected to be carried out on the 'I Will Always Love You' star later today.
