Authorities are investigating what caused the death of legendary singer Whitney Houston, who captivated audiences with her powerful voice while battling drug use and a rocky marriage with Bobby Brown.
Meanwhile, her 18-year-old daughter Bobbi Kristina was rushed to the hospital today to be "treated for stress and anxiety." She has been released. TMZ reported that Brown is on his way to Los Angeles to be with her. Saturday night, he remained on tour with New Edition and performed in Nashville, Tenn.
Earlier today, the Houston family released their first statement about the pop icon's untimely death.
"We are devastated by the loss of our beloved Whitney," they said in a statement through Houston's publicist. "This is an unimaginable tragedy and we will miss her terribly. We appreciate the outpouring of love and support from her fans and friends."
Brown also put out a statement today saying "I am deeply saddened at the passing of my ex-wife, Whitney Houston. At this time, we ask for privacy, especially for my daughter, Bobbi- Kristina. I appreciate all of the condolences that have been directed towards my family and I at this most difficult time."
On Saturday, paramedics found a lifeless Houston inside her hotel room bathtub at the Beverly Hilton hotel. TMZ reported that Houston's aides found her in the bathtub with her face underwater and attempted CPR before calling hotel security.
Officials were also unable to revive her. Beverly Hills police Lt. Mark Rosen said Houston was pronounced dead at 3:55 p.m, adding that there were "no obvious signs of foul play and no obvious signs of a cause of death." Los Angeles Coroner Office officials left with Houston's body around 1:50 a.m. PT.
An autopsy was finished today, but the coroner's office said a determination of cause of death would be deferred for up to six to eight weeks, pending toxicology and further testing.
A security hold was also put on the autopsy by detectives investigating the case, so no details about the autopsy would be released.
The coroner's office declined to speculate how Houston died when asked about reports that she may have drowned. When asked about drugs in the room, Ed Winter, with the Los Angeles County Coroner's office, said he could not comment on it. Winter also would not comment on the condition of the body or whether Houston was naked or not.
A source told KABC that a few presciption pill bottles were found in Houston's room.
Just hours before her death, Houston's mother, Cissy Houston, and her cousin, Dionne Warwick, reportedly both spoke to the singer and said there was no indication that anything was wrong.
Warwick spoke to her over the phone to check that they were seated at the same table at Davis' party, and Cissy Houston talked to her at around 3:15, TMZ reported.
Clive Davis Party
Houston was staying at the Beverly Hilton hotel to attend music industry executive Clive Davis' annual pre-Grammy bash.
It is the same event where she was introduced to the record industry nearly three decades ago.
Hours after her death, the party still went on but the scene was surreal.
The Beverly Hills crime lab was parked outside as paparazzi camped out waiting for Houston's body to emerge.
Her Final Days
Houston's final days were marked by questions about her sobriety. Her stay at the Beverly Hilton involved heavy partying, according to news reports.
A duet with Grammy nominee Kelly Price at a pre-Grammy party in Hollywood on Thursday would become Houston's final performance. Houston was at the party with her daughter having a good time. But photos show a disheveled, bloated and agitated Houston leaving. She reportedly had blood dripping down her leg, scratches on her wrist and had to be escorted from the club.
However, people who knew her said she was simply sweating from her performance.
"There was nothing wrong. There was nothing wrong. She was singing, she was dancing, she was laughing, she was playing," Price said. "I'm going to remember her just like that because that's the Whitney I always had the pleasure of being around."
