Beyonce: See "World's Most Beautiful" Without Makeup!

Beyonce Knowles is out to prove she's a natural beauty!

The same day People Magazine named her the World's Most Beautiful Woman, the new mom stripped her face of makeup.

Save for some lip gloss, Bey looked makeup-free ... and still gorgeous.

The secret to her beauty: Being a mom.

"I feel more beautiful than I've ever felt because I've given birth," she told the magazine. "I have never felt so connected, never felt like I had such a purpose on this Earth."
