I have figured out how Nicole Richie got so thin and stays that way. It's not the lack of eating. It's not drugs. And it's not anorexia or bulimia. Those aren't bracelets on her wrists, they're weights. Nicole's busy schedule of club hopping, shopping, and general celubutante duties don't afford her the time to hit the gym so she has to exercise on the go. Those huge hand bags she is always carrying? They're full of rocks. Oversize sunglasses? Made of lead. Her cellphone? Really a dumbbell.
