As far as Lauren Bacall, I'm of the mind that there may be some Parkinsons' going on because she was literally shaking. I don't know exactly how old she is but I guesstimate she's in her 80's.
As far as I know, Dolly's breasts are real. As a matter of fact, when she had all that cosmetic surgery about 15-20 years ago, I remember reading she had a reduction.
