Styledash has been covering the too-skinny celebrity debate for a while now. First there was the model ban in Madrid, followed by a similar measure in Milan, which consequently lead to some discussion of whether or not stylist Rachel Zoe's career would soon be coming to a close. And just like tragic clockwork, last week Nicole Richie entered a weight treatment center for what her publicist insists is "not an eating disorder." (Yeah, and Paris Hilton is "not a self-promoter.)In a recent interview with Vanity Fair, Richie admitted that she was "too thin" and was "not happy with the way she looked." But she despite her admission of a significant weight loss, Nicole has fiercely denied that she has an eating disorder, a claim that seems silly now that she has entered a treatment facility.
