2. Whitney Houston
Pop icon Whitney Houston battled drug addiction for many years. Following the separation and divorce from husband Bobby Brown, Houston’s family was hopeful that she would be able to turn her life around. However, that simply wasn’t the case, and Houston continued to struggle with addiction. One fateful night in a hotel in Los Angeles, Houston made the mistake of taking drugs and then getting into the bathtub. When she passed out, she slid under the water and accidently drowned.
