whitney & bobbi_kristina*On the heels of the death of Whitney Houston on Saturday, her daughter, 18-year-old Bobbi Kristina Brown, was rushed to Cedears-Sinai Hospital in Los Angeles, reports TMZ and People.

According to sources … Bobbi was taken out of the Beverly Hilton, where Whitney died yesterday, on a stretcher.

Bobbi Kristina was taken to Cedars Sinai Medical Center “because she was having a complete breakdown,” a source confirmed to People.

Bobbi Kristina was in the lobby of the hotel around the time when Houston’s body was pronounced dead at 3:55pm on Saturday.

Bobbi Christina is Whitney’s only child from husband Bobby Brown. Houston and Brown were married in 1992 and divorced in 2007.

Meanwhile …

The autopsy on the body of Whitney Houston will be performed today, Sunday, but any results will be deferred pending a toxicology report.

Although the cause of death is unknown, it is increasingly looking like Whitney may have fallen asleep or lapsed into unconsciousness in the bathtub and drowned.

Law enforcement sources tell us, Beverly Hills cops retrieved approximately a half dozen pill bottles from Whitney’s room … including Xanax. No illicit drugs were found.

Reports also say Houston had been drinking the night before and authorities believe a combination of Xanax and alcohol could have fatally sedated her.
