whitney houston*No illegal drugs have been found in the hotel room where Whitney Houston died Saturday afternoon, but prescription drugs were present, and it’s possible the she drowned in the bathtub, according to TMZ.

Sources tell us … when EMTs arrived Whitney’s body was already removed from the bathtub so it will take an autopsy to determine if she OD’d, drowned or died from some other cause.

Informed sources tell us … Beverly Hills cops — who were still searching the room at the time this story was posted — found various pill bottles. There was no evidence that Whitney was drinking alcohol in the room.

Whitney’s body was removed from the room on a gurney (see photo below).  It was taken to the LA County morgue for an autopsy to determine cause of death.
