Only someone as over-the-top as Lady Gaga could make posing au natural seem shocking.

Wearing absolutely no makeup, the 25-year-old "You and I" singer shows off her natural beauty on the cover of Harper's Bazaar's October issue (on newsstands September 27).

"Whether I'm wearing lots of makeup or no makeup, I'm always the same person inside," the singer confesses in the accompanying article.

Though she's known for her theatrical makeup and avant garde costumes, the pop star says it's fun to change things up. "I think what has been lovely about my relationship with the public is that they expect something unexpected from me."

The singer (real name: Stefani Germanotta) also shares her fitness secrets with the fashion mag. "I do yoga, I do Bikram and I run, and I eat really healthy. You know, my work sort of feeds me. I keep in shape by working hard."

Gaga even took up surfing during a two-day Mexican vacation in August. "I fell off a lot in the beginning," she tells Harper's Bazaar, "but one of the surfers said to me, 'Now that you can stand up, just look into the future and enjoy the ride.' I thought that was an interesting metaphor about life."
