Catherine Zeta-Jones Bares All

Catherine Zeta-Jones may be 40, but thanks to all her hard work, she’s still happy to strip down for a photo shoot without hesitation. “That's when your dancing days and being in theater pay off,” she tells Allure. “When you're doing a quick change, you don't give a shit who sees you.” She also discusses her relationship with husband Michael Douglas in the full cover story, on newsstands Tuesday.

"The only person I want to be in the trenches with is Michael. You know he's got your back,” she says, adding that she’s not 100% sure he wants to be in the trenches with her: "Probably not. Probably Kathleen Turner." (More Catherine Zeta-Jones stories.)
