Earlier this month, Jessica Simpson posed in the buff for Elle Magazine. While this mom-to-be isn’t the first to pose nude while pregnant, many celebrity moms before her have posed nude during their pregnancy and it seems to be a growing trend. It all started when Demi Moore posing for Vanity Fair Magazine in 1991, showing how her growing belly and new curves made her feel sexy. Today, many pregnant women say that they feel sexier and more empowered during their pregnancy than ever before, many for the first time in their lives. From Britney Spears to Paula Patton, to Cindy Crawford to Christina Aguilera, more and more pregnant women are saying that they feel sexier and more empowered during their pregnancy than ever before.
