I definitely don't agree with that. She not only looks every bit her age, but also worse than she should due to the surgical vandalism she's had done to her face:
Tom Cruise has probably gone under the knife too, but if he has, at least it was minor enough that he doesn't look like he's wearing a face that he cut off a corpse. Either way, I still think he looks his age.
Cosmetic surgery has never made anyone look/seem younger; not once, not ever. That's because younger faces look nothing like older surgically-altered faces. Plus you can still see the age in the rest of their skin, particularly on their hands; you can see it in the way they walk/move, and you can hear it in their voice.
