The coroner investigating Whitney Houston's death has said it is "too early" to determine what caused the singer's death.
Los Angeles County Coroner Ed Winter told reporters at a press conference that the investigation was waiting on toxicology reports, which could take eight weeks for the results to come back.
The singer was found "unresponsive" in the bath in her fourth floor suite at the Beverly Hills Hilton. But the coroner refused to speculate on rumours that Houston had drowned after bath water entered her lungs.
"I had a conversation with the family at the hotel and at no time did I discuss prescription meds or the drowning issue," he said.
"I don't know if the detectives discussed that with the family, but no, we have not released any information like that."
Whitney Houston's family and Beverly Hills Police Department would be the first to know why the singer died, the coroner told the press conference. He also said that there would be no restrictions on her family having her body, despite a security hold on the case.
The showbiz website TMZ reported that Houston died from an overdose of prescription drugs found in her room.
Medication, which included anti-anxiety drugs Xanax and Valium, mixed with alcohol, was the cause of Houston's death, the gossip website Radar Online claimed.
Houston was pronounced dead at 3:55pm local time on Saturday afternoon. She was due to perform at a pre-Grammy award party in Los Angeles last night.
Police in Los Angeles said that the soul diva and her entourage, which included friends, family and co-workers, had taken up a "fair portion" of the hotel's fourth floor.
"She was pronounced dead at the hotel and a number of people were able to identify her," Lieutenant Mark Rosen from Beverly Hills Police told the BBC.
Houston's daughter, Bobbi Kristina, was taken to hospital after the news her mother died. Paramedics said the 18-year-old's condition was not life-threatening and she has now been released.
Whitney Houston was the golden girl of the music industry at her peak in the 1980s and 1990s. She was also one of the world's best-selling artists.
Among her hits were How Will I Know, Saving All My Love for You and I Will Always Love You.
She won multiple Grammys including album and record of the year and her success carried her beyond music to movies like The Bodyguard.
But by the end of her career, drug use took its toll as her record sales plummeted and her voice became raspy and hoarse.
