Officials investigating the death of Whitney Houston say she may have drowned in her bathtub. The singer was found unresponsive in her tub at a Beverly Hills hotel. Radar Online and the New York Post quote anonymous sources saying Houston had prescription drugs in her room and may have fallen asleep in the bath after taking them. The Los Angeles County coroner's office said it performed the autopsy Sunday, but won't release any conclusions until toxicology results are finished, in six to eight weeks. Houston struggled with drug and alcohol addiction, and last year her spokeswoman had said she was headed back to rehab. Police say there is no indication of foul play.
