Believe it or not, Demi Moore has “excess skin and stretch marks.”

The 46-year-old actress, who has been slammed for denying having cosmetic surgery, has hit back at her critics and insists her body has changed since she became a mother.

Demi, who has three daughters with ex-husband Bruce Willis, took to the internet to address the comments she reportedly made during an interview with France’s Marie Claire magazine.

Referring to an old photograph that shows the Hollywood beauty sporting stretch marks, Demi wrote on her Twitter account yesterday, “I still have excess skin and stretch marks!”

She added, “Ahh hate to break it to you but I do. Comes with having a few kids 4 some of us! All this garbage that came out today about me is nothing more than an effort to diminish not just me but all women (sic).”

Demi also used her internet blog to urge her female fans to refuse to conform to ideals about their appearance and be proud of their bodies: “Diminishing us by continually measuring women based on how we look. Or dont look. Creating comparisons instead of connections Say no 2 that (sic)!”
