Whitney Houston's autopsy scheduled for today, daughter prevented from seeing body

The autopsy on the body of Whitney Houston will be performed today, but we’re told 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.
Whitney had been drinking the night before and authorities believe a combination of Xanax and alcohol could have fatally sedated her — although our sources say it is simply too early to draw any firm conclusions.
Whitney Houston was found in the bathtub of a Beverly Hills hotel yesterday with her face underwater, people close to Whitney tell TMZ.
According to our sources, her stylist, hairdresser and two bodyguards were among the people in the room at the time. We’re told they became worried about Whitney because she had been in the bathroom for over an hour and it was time to start getting ready for the Clive Davis party.
Our sources say they began to knock on the door and there was no answer. We’re told the hairdresser, who is female, went in to check on Whitney. She immediately screamed and, according to our sources, one of the bodyguards came running in and pulled her out of the tub.
We’re told Whitney’s face was below the water and her legs were up like she had slid down the back of the tub.
According to our sources, her body was very cold and the bodyguard attempted CPR. That’s when hotel security was called.
Paramedics arrived shortly thereafter, but Whitney was pronounced dead at 3:55 PM.
People close to Whitney Houston were aware she was taking Xanax and according to our sources, she told them she always took it before big performances like the pre-Grammy party she was scheduled to perform at last night.
We’re told Whitney believed the Xanax helped calm her nerves before going out in front of people. According to our sources, Whitney claimed to have anxiety and panic attacks and the pills helped her relax before taking the stage.
Our sources say the people inside of Whitney’s hotel room when she died were aware Whitney would take Xanax before shows. We’re told those people never saw Whitney take any pills, she would just tell them she did. They are unaware how many she would take or if she took any other drugs.
According to our sources, Whitney did not mention taking Xanax yesterday.
Our sources say Whitney had been in a good mood all day and was excited to be performing that evening.
Speaking just hours after the passing of Whitney Houston, legendary singer Tony Bennett said he feels with the rash of celebrity deaths recently, it’s time to legalize drugs.
Bennett performed at the Beverly Hilton last night Clive Davis’ pre-Grammy party, in an evening dedicated to Houston. Bennett told the crowd, “First it was Michael Jackson, then Amy Winehouse, now the magnificent Whitney Houston. Let’s legalize drugs, like Amsterdam, it’s a very sane city now.”
Davis, Houston’s mentor and producer, remembered her by saying, “Whitney was a beautiful person and she had a talent beyond compare. She graced this stage so many times. So simply put: Whitney would have wanted the music to go on.”
Jennifer Hudson is scheduled to perform a tribute in Houston’s honor at tonight’s Grammy Awards.
Whitney Houston’s daughter Bobbi Kristina got into an angry shouting match with police officers outside the hotel room where her mother was found dead, TMZ has learned.
According to law enforcement sources, Bobbi Kristina showed up on the 4th floor of the Beverly Hilton several hours after Whitney’s death. We’re told when officers informed her no one was allowed to see the body, BK screamed, cursed and demanded to see her mother.
Ultimately, she was not allowed into the room and left. We’re told Whitney’s cousin Dionne Warwick also showed up later. She too was turned away by officers.
As we reported earlier, other family members and friends, who were in the room when authorities arrived, identified Whitney’s body.
