Very sad 
I always thought she led such a charmed life. Poor girl. My heart goes out to them both. I do wonder what happened, though. In this case and others that come to mind. And not just because I am nosy. From what I understand of obstetrics, it is very often a case of incompetent cervix when one loses a baby at around the 5 month stage.
I hope they manage to find out the cause and have another baby soon.
