Is the divorce getting to him?

Paul McCartney did an impromptu photo shoot and politely asked the paparazzi to leave him alone while in a New Jersey suburb. I wonder if his divorce from Heather Mills is finally getting him? (He totally disses that old lady who can't believe Sir Paul McCartney is in her hood) I know I would be pissed off if my soon-to-be ex-wife was a gold digger trying to take me for 80 million pounds and trying to dig up dirt on a previous marriage with a wife who is deceased, forcing me to blow 200,000 pounds on old recordings of her that she planned to use against me. Can't the Queen step in or something? The guy is a knight, she can't sweep this one under the rug?
