Whitney Houston's official cause of death has been ruled as "drowning and effects of atherosclerotic heart disease and cocaine use," Breaking Celebrity News is reporting.

The singer's toxicology report was released by the L.A. County Coroner's office Thursday, and stated that "Cocaine and metabolites were identified and were contributory to the death. Marijuana, Alprazolam (Xanax), Cyclobenzaprine (Flexeril) and Diphenhydramine (Benadryl) were identified but did not contribute to the death."

The official ruling contradicts earlier media reports that no water was found in Houston's lungs at time of death and that she had not drowned.

Houston was 48 when she passed away on February 11 at the Beverly Hilton Hotel the night before the Grammy Awards.

Bobby Brown’s ex wife’s unresponsive body was discovered by members of her entourage in the bathroom of her hotel room and she was pronounced dead by responding paramedics at 3:55 p.m. PST.
