I think she's had work done in the past just not to the extent as other celebs and most likely didn't or doesn't keep up with it constantly like some do. Weight loss, stress, sadness, divorce , etc all show on your face. So I think she looks pretty good, yet still real enough kwim?
Maybe she could get a laser treatment or 2,a filler touch up ( little ) but I honestly don't think she needs a huge overhaul or anything.
I do prefer the longer hair., or shoulder length she has had in the past. Not the super short do. It's too matronly on her.
