One of the most prominent stars singled out for having an unhealthy obsession with staying trim is Nicole Richie. Now the socialite has caused even greater controversy after word was leaked that she'd organized a Memorial Day party for only her skinniest friends.

Her email read: "There will be a scale at the front door. No girls over 100 pounds allowed in. Start starving yourself now."

The public is already bombarded with unrealistic, unobtainable, and downright unhealthy ideas of what it means to be fit and attractive. Whether she likes it or not, Richie and her unnaturally slender frame are contributing to that. She's since claimed the email was a joke, but -- especially for someone in her position -- I can't imagine how it could've been funny.
