Jennifer Lopez may be having the best year ever.

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."

On dieting, she said, "The thing is, it's part of my job. I don't want anybody thinking it's easy. It does take time and it's hard work. HDTV wide-screen is nobody's friend!"

Considering how good she looks on 'Idol,' we imagine they're getting along pretty great.
