The X Factor's sassiest judge, Demi Lovato, is once again slaying us with her devastating good looks and this time she's going au natural! Demi recently took part in People's 2013 Most Beautiful shoot (because, duh, she's the most beautiful ever), and home girl went completely makeup free. One word: flawless!

"When I'm not working, I wear as minimal of makeup as possible," Demi tells People during a behind-the-scenes video of her photo shoot. "When I don't have makeup on, I feel confident."

Demi definitely doesn't need makeup (her skin is clean, clear and under control!), but the secret to her healthy glow? A simply nightly skincare routine!

"First thing I do is wash my face," Demi says. "I use all of Renee Rouleau products. I wash it with an exfoliant gel, and then I use a toner, and then I put moisturizer on, and then I put sunscreen on, and I do eye cream."

We are so there. By the way, Demi has a few sage words of wisdom for her fans — always wash your makeup off before bed, otherwise the residual coverup might age you!

Sigh, one more reason this gal is our muse....
