What makes her so darn beautiful?

Normally I don't gravitate towardd 'milfs' but sweet baby jesus is this lady enchanting. What makes her get your engines going?

I guess for me is she obvious has a great figure, a stone cold killer smile, grace, class and confidence. I think most actresses her age try to act way sluttier, and even if they have mint bods, it comes off unappealing and trashy (biggest one to mind Jennifer Anniston in Vacation).
