At 46-years-old Demi Moore is the very image of age-defying beauty - but it's no secret that Mrs Kutcher has indulged in the odd nip tuck over the years.

Star magazine claims that the screen siren's youthful looks are the result of a combination of soothing honey treatments for her skin and olive conditioners for her hair.

However, Demi's fuller face suggests that she may have enlisted the help of her plastic surgeon one more time.
