Seventeen magazine has signed on a cluster of stars to promote its Body Peace Treaty, which encourages teenage girls to stop hating themselves. A worthy goal, but I have a beef with the approach.

First, among the celebrities who’ve pledged their souls to this project are notorious former drug addicts and anorexics. They’re supposed to be role models?

Second, the treaty’s aphorisms are directly contradicted throughout the rest of the magazine:

• “Know that I’m already beautiful just the way I am.” But you too can win a trip to fat camp.

• “Quit judging a person solely by how his or her body looks — even if it seems harmless — because I’d never want anyone to do that to me.” But cast your vote on who’s hot and who’s not.

• “It takes a lot of airbrushing, dieting, money, and work to look like that.” But here’s a slideshow of the most glamorous celebrity looks for you to aspire to.

Never mind the exhortation on this month’s cover to “Look Pretty Now!” Is that an order?
