Alluring Hollywood Women Bare All

As the temperature rises, these celebrities are showing that skin is in for an Allure photo shoot. The magazine calls the vivacious ladies "Venuses for a modern age.” Catherine Zeta-Jones, Kara DioGuardi, and Colbie Caillat are just some of the stars who go au natural for the spread.

Colbie and Kara called the experience "liberating." In addition, Colbie admitted, "I was afraid to do it, but I saw what this shoot meant: We all have our insecurities; we just can't let them stop us from doing what we want in life."

Regina Hall, Jessica Capshaw, and Emmanuelle Chriqui also stripped down to their birthday suits for the issue, on newsstands April 20.
