Interesting. He mentioned something about not liking mirrors in an interview, maybe he just isn't comfortable with the whole posing/looking good/capturing the moment - thing?
I think, he is cunning a little, having at that every reason to be satisfied with the way he looks.
Just feels uncomfortable, being a focus of attention. Can't you see all those apparent attempts to drag out someone else onto the stage, whether Nigel or Ruth, to make himself as inconspicuous as possible and switch attention to them?
