Nicole Richie's diet pill addiction

Nicole Richie's frightening weight loss was caused by an addiction to diet pills. The brunette's close friend Crystal has revealed the 'Simple Life' star is hooked on Hoodia - a South African herb that fools the brain into thinking you are constantly full. She told Britain's More magazine that Nicole once told her: "Hoodia makes you look hot in low-cut tops and backless dresses. It is good for me - the bushmen have sworn by it for hundreds of years and that's good enough for me." The troubled 24-year-old dropped from a US size 2 to a US size 0 in a matter of months following her brief split from Adam Goldstein last December and she recently confessed that she was too thin. The pair reportedly split again this week as a result of Nicole's constant partying and worrying eating habits.
