Whitney's body was found ravaged by scars, cuts and had 11 teeth missing.
Years of drug and alcohol abuse had also left her with a weak heart and liver, a hole in her nose, and eleven false front teeth, the Sun reported.
She even had a needle mark on an arm and was high on a cocktail of nine drugs when she died in a hotel bath in LA.
Grisly evidence from police and medical teams revealed for the first time shows how swathes of skin were burnt off Houston's back as she plunged into the scalding water.
It also resulted in "skin slippage" on her legs. Sources said that the temperature could have been 66 degree C when she climbed into the tub. Six hours after her death, the water was still 33 degree C.
According to medical sources, she may have been so out of her mind on drugs that she did not notice how hot her bath was.
A spoon covered with cocaine was found in her hotel suite at the Beverly Hilton hotel. Traces of the drug were found in her system plus marijuana, anxiety pills Xanax, muscle relaxant Flexeril, allergy medicine Benadryl and painkiller Ibuprofen.
The 48-year-old was also scarred by decades of cosmetic surgery, booze-fuelled fights and falls, and possible suicide attempts.
She had marks on her stomach, chest and upper left thigh believed to be from cosmetic procedures including breast implants.
The singer had a scar on her inner left forearm that sources claim may have been self-inflicted. Days before her death, she stumbled out of a Los Angeles club with her legs and arms dripping blood.
Friends claimed that she tried to slash herself to death in the toilets after seeing her on-off lover Ray-J chatting to other women.
The pop star, who had an abusive 14-year marriage to singer Bobby Brown, was also covered in small bruises and cuts.
Some were caused by possible falls in the bathroom where she died and by desperate attempts of her assistant, bodyguard and paramedics to revive her.
Houston's lifestyle had weakened her heart so badly that one of her coronary arteries had narrowed by 60 per cent.
Years of taking coke also caused mouth and nose problems. Autopsy reports said that she had a "perforated posterior nasal septum" - just like former coke addict actress Danniella Westbrook.
An investigator also noticed an old needle puncture wound on Houston's inner left elbow. And she was wearing a "maxillary dental prosthesis" with 11 false teeth - probably caused by coke rotting her gums.
The official cause of death was declared to be accidental drowning with heart disease and cocaine use as contributing factors. ( ANI )
