“I don’t believe in having work done, because then everybody looks the same.”
Liar! Look at these photos taken of her over the years. I definitely detect a few facelifts (look at how her hairline has moved back and yes, I know she often wears wigs). I also think her lips have lost fullness and are plumped up with collagen to recreate the fullness of her youth.  In addition, I suspect she has had work done around her eyes. However, she still looks good for being 75.
