She's definitely had something done with her teeth and/or jaw line. In all her earlier pictures, her top gum line was very visible; now it's not. I don't know how it was done, but it changes the look of her face.
And, sorry to say, but to me her nose looks like she's had too much done. (A la Michael Jackson. Looks at those comparison photos. In the newer one, her nose looks like it's collapsed a bit on her left side - but that could just be the angle.)
Too much cosmetic surgery, no matter what line of business you're in, is not a good thing. We all know that people age! Unless you're Dorian Gray.
