UPDATE: Whitney's Daughter Bobbi Kristina Has Been Released From Cedars-Sinai Medical Center.
Whitney Houston's 18-year-old daughter, Bobbi Kristina, was hospitalized just after midnight — this was BEFORE she was rushed to Cedars-Sinai Medical Center for a SECOND time Sunday afternoon, a family source has confirmed to Star magazine and RadarOnline.com.
"She tried to ease the pain of losing her mother by having a few alcoholic drinks," the insider said.
"She was distraught, on the verge of a complete breakdown. Not knowing what to do, members of her mother's entourage tried to calm her down with a sedative. The two were an unfortunate mix and she ended up passing out."
As we first reported via Twitter in the early hours of Sunday morning, the Beverly Hills Fire Department requested a rescue and engine to the same floor of the Beverly Hilton where Houston, 48, was found dead to treat another "person who is ill," a law enforcement source confirmed.
The call was made just after midnight.
RadarOnline.com reporter Amber Goodhand confirmed at the time, the patient was transported to a local hospital.
The cause of why Bobbi Kristina was transported to Cedars on Sunday afternoon -- for a second time -- is not yet known.
Bobbi Kristina was reportedly in the lobby of the hotel around the time when Houston's body was pronounced dead after being discovered in room 434 at 3:55 p.m.
The Grammy-award winning songstress was found partially submerged in the bathtub of her room.
"Bobbi Kristina was screaming, 'What's wrong with her? What's wrong with her?," another source told People.
