I am not particularly engaged by 'celebrity' stuff, but what I notice is how very difficult it is becoming to tell many of the women apart - they all seem to combine very shiny tight faces, ski-slope nose and strangely spread-out lips - but in addition the continual subtle 'work' that they have done means that the likes of me, dipping inot photos from time to time, sees someone whose face is simply not the face they started out with.
I looked at a few minutes of Cougar Town t'other evening - Jennifer Aniston's face is simply not the same person as the JA who was in friends. It isn't that the face has aged - not a line in sight - but the chin / eyebrows / mouth / eye angle have all changed.
Goldie Hawn is a spectactular example of this: if you did not have a label telling you it is her, there is very little resemblance between the face of the Rowan and Martin's good-time girl to the present person's face.
