A fatal cocktail of prescription drugs and booze killed Whitney Houston before she became submerged in a bathtub, the singer’s relatives reportedly were told.

The Los Angeles County Coroner’s Office does not believe the “I Will Always Love You” star drowned, contrary to earlier reports suggesting she slumped beneath the water in a drug-induced stupor, TMZ.com reported Monday.

Coroner’s officials told Houston’s family she did not have enough water in her lungs to suggest she drowned and was likely dead already.

An autopsy was performed Sunday, but the results of a toxicology test are likely to take several weeks.

There was no evidence of foul play.

The 48-year-old’s shock death Saturday made her the latest in a string of celebrities to overdose accidentally on legal pills, including Anna Nicole Smith and Heath Ledger.
