Demi Moore, 56, Stuns in Naked Cover Shoot for Harper’s Bazaar

The actress just stripped down for the October cover of Harper's Bazaar. It's her first time posing in the buff since her famous Vanity Fair cover in 1991, when she was pregnant with Scout.

Moore sat down with friend Lena Dunham for the cover story, opening up about sensitive topics, including her sobriety.

Lena writes that Demi found sobriety in her 20s, lost it in her 40s, and got clean again in her 50s.

Demi told her, “In retrospect, what I realized is that when I opened the door [again], it was just giving my power away. I guess I would think of it like this: It was really important to me to have natural childbirth because I didn't want to miss a moment. And with that I experienced pain. So part of being sober is, I don't want to miss a moment of life, of that texture, even if that means being in… some pain.”

Moore gets even more candid in her new memoir “Inside Out” as she pulls back the curtain on her career and personal life, including high-profile marriages to Freddy Moore, Bruce Willis and Ashton Kutcher.

“Inside Out” and the new issue of Harper's Bazaar will be available September 24.

“Extra's” Billy Bush and Jennifer Lahmers took on today's top headlines, including Kevin Hart's big health update and Demi's nude cover shoot. Watch!
