The actress-turned-singer-turned-reality TV host, who can currently be seen as one of three judges on FOX's 'American Idol,' was named PEOPLE's Most Beautiful Woman, the magazine revealed today.

In the issue, on newsstands Friday, Lopez talks about dieting, her two twins and how she loves being a no-makeup kind of mom.

"That's when I'm my happiest," she told the magazine. "Just being able to touch my face and rub my eyes and put my fingers in my hair and not having to worry about messing it up. It's so much better."
