(TMZ) TMZ has obtained the 911 call placed moments after Whitney Houston's body was discovered in a bathtub at the Beverly Hilton hotel last month.In the tape, the caller -- a member of the security team from the Beverly Hilton -- reports a 46 year old female who was found in a bathroom at the hotel.
At first, the caller is unsure if Whitney was breathing ... but later reports she is not breathing.
The security member says he was alerted to the situation by a female who was in the room ... and says the woman was "irate" and kept hanging up on him.
As we previously reported, Whitney's official cause of death is listed as "accidental drowning" -- but heart disease and cocaine use were contributing factors. According to the final autopsy report, Whitney may have overdosed.
According to the L.A. County Coroner, Whitney's chronic use of the drug caused a narrowing of her arteries, which resulted in a cardiac event before her death. Listen here.
