Whitney Houston's death could have been the result of drowning in the bathtub, reports have revealed.
The legendary singer was pronounced dead in a fourth-floor hotel room on Saturday afternoon, with no immediate apparent cause of death. Beverly Hills Police Department's Lt Mark Rosen revealed that there were "no obvious signs of criminal intent" at a press conference shortly afterwards.
US website TMZ are now reporting that prescription drugs were found in the star's room, with "various pill bottles" spotted.
An insider also told the publication that when Emergency Medical Technicians arrived at the scene "Whitney's body was already removed from the bathtub so it will take an autopsy to determine if she OD'd, drowned or died from some other cause".
There is no evidence to suggest Whitney was drinking alcohol in the room.
The 48-year-old musical icon was removed from the hotel room on a gurney and will now be taken to the morgue for an autopsy to determine the cause of death.
Whitney had a celebrated career in the 80s and 90s but later hit headlines for her tumultuous marriage to Bobby Brown and her battle with drugs.
She had one child, daughter Bobbi Kristina, 18, from her union with the singer.
TMZ have also reported that Bobbi got into an "angry shouting match" with police officers outside the hotel room where her mother was found. Law enforcement sources say the teen "showed up on the 4th floor of the Beverly Hilton several hours after Whitney's death."
When officers denied access to Whitney's body, Bobbi reportedly "screamed, cursed and demanded to see her mother."
According to reports, she was ultimately not allowed in the room. Whitney's cousin Dionne Warwick showed up later on and was also "turned away" by enforcement officers.
Meanwhile, it has been reported that Jennifer Hudson will lead a tribute to the star at tonight's Grammy Awards.
Whitney was a six-time Grammy winner, and insiders say the show's producers are keen to present a fitting tribute at the ceremony later today.
According to Ken Ehrlich, the show's executive producer, the plan is to honour Whitney's life with a "respectful musical tribute," says e! Online.
"It's too fresh in everyone's memory to do more at this time, but we would be remiss if we didn't recognise Whitney's remarkable contribution to music fans in general, and in particular her close ties with the Grammy telecast and her Grammy wins and nominations over the years," he added.
Many stars have taken to their Twitter pages to express their grief at the loss of such an iconic and influential musician.
"I feel sick.... Life is precious, we are fragile souls. Let's love each other! I miss you beautiful Whitney, the whole world misses you!! (sic)" Alicia Keys exclaimed.
Singers Jennifer Lopez and Pink also voiced their sadness over Whitney's untimely death.
"Such a loss. One of the greatest voices of our time. Sending out prayers to her family... #R.I.P.Whitney," Jennifer wrote, with Pink adding: "Whitney was the reason many of us do what we do. "a few stolen moments is all that we share" RIP (sic)."
