Uneasy lies the head next to the head that wears a crown

I sense a theme here--two headlines spotted today in the supermarket checkout line, composing the entire front page of the tabloid the Globe:

Camilla Runs Back to Ex-Hubby

Laura Bush's Nervous Breakdown: "I can't take any more," she tells Prez

I assume "Prez" isn't Elvis Presley--last spotted, I believe, in my local Store 24.
