the kick didn’t wake up Whitney Houston

When Whitney Houston was found dead on Saturday at the Beverly Hilton at the age of 48, early reports suggested she may have fallen asleep or blacked out in the bathtub and drowned. Oh but you'll never guess why she blacked out. Not in a million years.

Whitney Houston's family was told by L.A. County Coroner officials she did not die from drowning, but rather from what appears to be a combination of Xanax and other prescription drugs mixed with alcohol ... this according to family sources (and TMZ).

Which Radar pretty much confirms:

Houston had "a plethora of sedatives including Lorazepam, Valium, Xanax, and a sleeping medication that was found in her hotel room," a law enforcement source tells us.

So there you go. Whitney Houston got drunk and high and drowned. It's like if Tyler Perry had made 'Inception'.
