Looks like America’s sweetheart has discovered the secret to skipping the aging process.

PEOPLE Magazine recently named the 50-year-old screen siren as 2015's World's Most Beautiful Woman, and we couldn't agree more. What's really surprising, however, is how Bullock apparently stopped aging.

What’s the secret behind the 50-year-old’s seemingly ageless features? Back in 2000, Bullock told InStyle Magazine that she’s really low-maintenance when it comes to her beauty regimen.

“I use a face cloth and Artistry cream,” admitted Bullock. “I put mascara on today because I wanted to make a bit of an effort.”

However, Bullock did reveal a no-nonsense workout routine, which could explain those gorgeous gams.

“I do Pilates, kickboxing, weight training, and when I’m at home, run or ride a bike,” she said. “If I can work out every day, I will.”

And considering she's got a 5-year-old son Louis, this actress has plenty to keep her busy — and her efforts show.
