I've never seen her before, only heard her on the radio, so I was surprised to see how she looked as photos I've seen of her would have been when she was much younger, I had no idea she was this age either. My first impressions were, isn't she small, why is her hair such a mess, and why is she wearing sunglasses. As others have said though, she is a bit wacky so if this is how she looks now, then so be it.
I just googled her. Not sure what all the fuss is about, but she looked like a normal and probably feisty 77yr old to me. And not particularly wacky either.
