Thought this was pretty interesting. It is from this week's US Weekly.
Designers Say No to Devil
Does the devil really wear Prada? Rumor has it that Vogue editor Anna Wintour, 56, threatened to blacklist designers who participated in the June 30 movie about a boss from hell said to be based on the powerful fashionista. While a Vogue rep calls the rumor a "total fabrication," The Devil Wears Prada stylist Patricia Field admits "some designers didn't participate" (a rep for Jean Paul Gaultier says he opted out because they were "concerned with the content"). But Field, who worked with the Sex and the City cast, did work with top labels, including Gucci, Valentino, and yes, Prada. Says Field, "There are so many clothes out there that if somebody doesn't want to work with you, it's not like your life has ended."
