That's what I noticed first, too. And second, her hands have been enlarged. I met her in person, as many of us have, and she's a small person with small hands. I'm not large (5'5" and 125 lbs), and her hand is smaller than mine. It's not even a very good job - you can tell at the wrists - and I think she always wears her wedding ring. (Maybe I'm wrong?) I don't do photoshop but I can do these things in Paint Shop Pro. Yes, the picture has been messed with. But try as they might, it doesn't get their desired effect, does it? :-)
In the photos of her at Rolling Thunder, she does not have on a wedding ring. Maybe she was bloated the day the photo was taken? (you women know what I’m talking about)
