From chopping off her hair into a short pixie in 2010 to rocking dramatic Black Swan-inspired eye makeup at this year's Harry Potter and the Deathly Hallows Part 2 premiere, Emma Watson is no stranger to experimenting with her look.
But even the gorgeous Brit, who always appears polished and chic, admits that even she's prone to a makeup mishap from time to time.
"Wearing too much makeup has been my biggest beauty faux-pas," she told Britain's Hello! magazine. "I truly, truly believe that beauty is something that comes from within. You can only really look beautiful if you feel beautiful on the inside. It shows through your face, the way you move and the way you hold yourself."
Watson goes on to admit that despite her down-to-earth approach to outer beauty, she still covets cosmetics.
"The funny thing about me is that I do have a lot of products -- I've always loved makeup and its ability to transform you," she said. "But I don't actually wear a lot of it, so there is an irony that I own so much of it but wear so little. But I do love beauty products."
And besides skipping the layers of makeup, Watson's other live-by beauty rules are: "Don't over-pluck your eyebrows and always take your makeup off before you got to bed!"
