Sexy film stars Carla Gugino, Vanessa Williams and R+B singer Cassie have stripped for a sexy new photospread in women's magazine Allure. The trio joined Marley Shelton and Kristin Chenoweth for the 'What Lies Beneath' special, which appears in the May (07) issue of the glossy publication. Shelton admits she only agreed to pose naked, sitting on a tree stump, after pal Gugino bared all for the spread first. And Gugino reveals her boyfriend was thrilled when she told him the spread would feature her and Shelton: "He wrote back, 'I'm hyperventilating.'"
