It was the baby bump that launched a dozen copycats. Moore was seven months pregnant when she posed for Annie Leibovitz in little more than a diamond ring and a strategically placed hand. Naked wasn’t new, but a nude natal model was. Timing was key—the covered-up ’80s were over, Moore was a big star and married to the equally-famous Bruce Willis, and the public was ready for a new view of pregnancy, whether they wanted it or not. Despite the potential for harsh backlash in the media and in sales, then Vanity Fair editor Tina Brown ok’ed the image over others that showed Moore with more clothing. The risky choice paid off; it became a best-seller and one of Leibovitz’s best-known images. Since then, many cover models from Britney Spears to Claudia Schiffer, have stripped down to Moore’s size.
