For the magazine's May issue, DioGuardi took it all off, along with four other celebrities, including Entourage's Emmanuelle Chriqui, Grey's Anatomy star Jessica Capshaw and singer Colbie Caillat.

"This shoot was less about beauty than about taking a risk and showing people a side of me they never have seen," says the Idol judge.

The 39-year-old also explained how's she's changed since her struggles with binge-eating and depression in her early 20s.

"Back then I was a size 6 or 8; now I'm more like a size 2," she says. "Food is not what I use to anesthetize myself anymore."
