Demi Moore's upbringing was colorful, to say the least. The acclaimed actress grew up with an alcoholic mother (whom she completely cut off in 1990 after she walked away from a rehab stay Moore had paid for) and a stepfather who committed suicide ten years earlier. She attended high school, but eventually dropped out during her junior year to work at a debt collection agency. She went on to try her hand at a modeling career and acting, but really hit it big with 1990's haunting Ghost.
