Billie-Jo,
I don't think that the changes in the pre-nup should be read into any further than need be. It had some changes made to it, but it does not mean that Mary and Fred have hit a patchy or rocky area in their marriage. As far as I'm concerned, they seem very happy and as much in love as when they married. Actually, I think they seem even more in love than when they married! Just take a good look at all of the pictures of them...So don't be worried. Let's enjoy all the great pictures we get of this happy family!
