WARNING: This is not for the faint of heart.     Or, for fans of certain celebrities including Wayne Newton or Priscilla Presley.

        Celebs are constantly in our face--slim, trim, age-defying stars who we loved when they were young and who we marvel at in middle age.     They seem to keep looking better and better, while our mirrors at home tell us another story.    Sags.    Bags.     Wrinkles.    Too much hair in some spots.    Not enough in others.     Gray hair all over.

       MSNBC lifts the lid on some 20 stars who've either learned the secrets of better biology, or who hooked themselves up to some pretty high priced Hollywood scalpels and needles.     You be the judge as to the results.
