Tragic pictures released of the hotel room in which Whitney Houston died show remnants of her final meal - a hamburger, fries and a turkey sandwich - which she is said to have eaten in the bathroom right before she died.
The pictures also show the star was drinking champagne and beer shortly before her death and it is suggested the lethal combination of alcohol with prescription drug Xanax - which was also found at the scene - could have been the cause of her death.
It comes as Houston's doctors reportedly face questions over whether she obtained the drugs found in her Beverly Hill Hilton Hotel room illegally.
According to the Daily Mail, the body of the singer, 48, was found in a bathtub at her suite on Saturday, surrounded by different bottles of prescription pills including ibuprofen - a painkiller, Xanax - an anti-anxiety drug, Midol - for menstrual cramps, amoxicillin - for bacterial infections and several others.
County coroners will request copies of the late singer's medical records and will compare them with prescription bottles found in the hotel room, a source told the British newspaper, The Sun.
If anyone gave Houston the drugs illegally, they could be charged. '[Authorities] need to determine that no one is criminally negligent. There still could be charges in this case,' the source said.
The reports come as Houston's body landed in New Jersey for a funeral to be held at the end of the week, the Associated Press reported.
Her family is said to be considering holding the funeral at Newark's Prudential Center, which hosts college and professional sporting events and seats a staggering 18,000 people.
Photographs taken on the night of her death show a tray on the floor of the bathroom which is said to have contained the turkey sandwich and jalapeños. A Gilette razor, glass of water and items of clothing are also strewn on the floor.
Family sources told TMZ Whitney ate the burger and fries in the hotel suite before taking the turkey sandwich and jalapeños into the bathroom where she planned on eating them after her bath.
Coroners have still not ruled a cause of death but there are fears she may have died - perhaps from a mixture of drugs - before she became submerged in the bath where her body was found.
TMZ reported that some of the prescriptions were filled out at the infamous Mickey Fine pharmacy, which was raided in 2009 by the DEA for evidence of 'improper dispensing of controlled substances', in connection with the death of Michael Jackson.
These reports have yet to be confirmed.
One of the drugs Jackson was said to have received from there was the highly addictive Demerol - one of the drugs which was alleged to have contributed to his death - and that agents believe the Beverly Hill's pharmacy may have refilled prescriptions without a doctor's authorisation.
Mickey Fine's is thought to have been the go-to pharmacy for both singers who are believed to have spent thousands of dollars there.
According to TMZ, Mickey Fine also sued Jackson in 2007 for non-payment of a bill of more than $100,000.
Some of the prescriptions found in the crack cocaine user's hotel room were reportedly issued in 2011, but some were believed to have been more recent.
The amoxicillin was recently prescribed to Houston for a sore throat, sources told TMZ.
A coroner ruled today that it was impossible to ascertain the exact cause of the singer's death but ruled out foul play.
Her family was allegedly told by Los Angeles County Coroner officials there was not enough water in her lungs to conclude she had drowned in her luxury hotel bathtub and in fact died before her head went under water, said gossip website TMZ.
Many sources say her death was a result of drugs but are not ruling out natural causes.
Los Angeles assistant chief coroner Ed Winter refused to go into details and said toxicology reports will not be available for several weeks, making it impossible to pinpoint the exact cause of death.
He confirmed to ABC that officials found prescription bottles, but said there wasn't anything 'alarming' or 'out of the ordinary' about them.
Though there were reports she had drowned, or overdosed, he said they won’t make a final determination until 'all the tests are in'.
He said: 'I had a conversation with the family at the hotel and at no time did I discuss prescription meds or the drowning issue.
'I don't know if the detectives discussed that with the family, but no, we have not released any information like that.'
Asked by reporters whether he ruled out drowning because there had not been enough water in the singer's lungs, as was earlier reported, he said: 'That did not come from us. It's too early to say. The autopsy was done yesterday and there still is additional testing that is ongoing.
'You can look at a body and not know what the cause of death is. You might have a suspicion that person could have suffered a heart attack or something.
'No matter what medications they're taking, until we run a (toxicology test) and see the level and what's in the system, we're not going to speculate.'
Law enforcement sources said it is possible the singer suffered a heart attack as a result of the cocktail of drugs she had taken.
It took nearly three months for the coroner to officially rule on Michael Jackson's death which was eventually determined to be from 'acute propofol intoxication' and two other drugs.
Whitney Houston's body was released to her family on Monday.
Her funeral will be held in Newark, New Jersey, later this week, NBC New York reported.
Sources told the Associated Press that her body landed there on Monday night. They said the family had suggested there could be a wake on Thursday and a funeral on Friday for the star.
It comes as President Obama on Monday said his thoughts and prayers were with Whitney Houston's family, especially her daughter.
Press secretary Jay Carney spoke on behalf of the White House, saying the president said it was hard not to be an admirer of the singer's 'immense talent'.
He added that it is a tragedy to lose somebody so talented at such a young age.
Sources tell TMZ the actor rushed to the LA hospital Whitney was taken on Saturday as soon as he heard about her death, and immediately offered up his private plane to the family.
Houston was born in Newark and raised in East Orange. She got her start as a singer in the choir at New Hope Baptist Church in Newark.
Mourners have been flocking to the church since her death, with local Shawn Cooper saying yesterday: 'The Houston family means a lot to this community, they have done a lot for this community, and being there for them is the best thing we can do as a community today.'
She may be buried alongside her father, army serviceman and entertainment executive John Houston, who died in 2003 and was laid to rest at Fairview Cemetery, Westfield, New Jersey.
The Queen of Pop was found dead hours before she was due to attend a pre-Grammy awards party thrown by long-time friend and mentor Clive Davis.
