Brittany Murphy weighed 115 lbs. when she was found dead Dec. 20 at age 32, Los Angeles County Coroner’s Office Chief Investigator Craig Harvey tells

The 5' 3" actress -- who died of pneumonia "exacerbated" by multiple drug intoxication -- "wasn't the healthiest person in the world," Harvey tells Us.

Despite her emaciated appearance, Murphy's husband Simon Monjack has denied reports that the actress suffered from an eating disorder.

He also slammed rumors that Murphy suffered from prescription drug problems.

A number of prescription drugs were found on her nightstand, but Monjack has said Murphy was only taking the painkiller Vicoprofen and Fluoxetine, an antidepressant to treat her menstrual cramps.

Harvey told Us the specific drugs found in Murphy's system "will be contained in the toxicology report," due in a few weeks.

Murphy's death has been ruled accidental.

Monjack has blamed Hollywood for the actress' demise.

"You want to know what broke Brittany Murphy's heart?" he asked Larry King in an interview last month. "Hollywood broke Brittany Murphy's heart."
