Websites like Media Take Out are implying singer Rihanna had a drug overdose and it's being covered up. The promiscuous singer, who has been seen doing cocaine and marijuana, much like the late Whitney Houston, has been very depressed lately over her turbulent relationship with the love of her life Chris Brown and career pressures, stemming from declining sales.

Brown was spotted with another woman again, who came forward bragging about having sex with him at his house in Los Angeles. She is the fifth woman he has cheated with this month. Rihanna recently cancelled a third concert date, this time Houston, citing a mysterious "illness." This is often codeword in Hollywood for drug and or alcohol issues.
