She came close to showing it all off on the American Idol stage last May, donning a bikini on the season eight finale.
But Kara DioGuardi takes things one step further in the latest issue of Allure. Actually, two steps: the bottom and the top. She appears totally naked in the magazine.

DioGuardi isn't the only celebrity to bare it all for Allure. Wanna see an Entourage hottie and a Grey's Anatomy beauty in the buff? Read on.
