Is age really just a number, Demi Moore?

The actress is defending her 47 years on Twitter.

The star posted a picture of herself from a Harper`s Bazaar shoot she was doing on Santa Monica beach, which got her Twitter users posting some comments.

Demi wrote: "Had the priviledge of working with a giraffe yesterday he was beautiful gentle and so amazing." (sic)

Other Twitter users then posted comments, with one writing: "sorry Demi that your self esteem is so low you can`t admit to a little Photoshopping."

A while later, someone else Tweeted: "sorry but you look old. specially your neck & cheecks at the second shot." (sic)

Demi then replied, writing: "I`m 47, how am I supposed to look?"

But not everyone felt the same, as one user Tweeted: "WOW you look beautiful!!"

Another gave Demi words of support saying: "never let those who try 2hurt U in..we all feel small sometimes Know UR fabulous loveable &Wanted!" (sic)

Not very festive behaviour from Demi`s critics, is it?
