It seems to me that whenever I'm in line to pay for my groceries, and whenever I go on Yahoo, I encounter celebrities "opening up" -- about the disgraceful acts of people who had trusted them to preserve their privacy. I have not actually read the articles, but they always seem to be about gross behavior (abuse or drug addition or perversion or something) on the part of parents, husbands, wives, or children.
The expression "opening up" has a positive connotation and does not seem to be the correct word for what these people are doing -- divulging other people's embarrassing secrets for money, or perhaps pretending to do this by making stuff up.
But what would be the correct word? "Angelina finally _____ [betrays Brad's trust and humiliates him for money] about Brad." It seems like some slang words (like sells out, rats out) come close. When I look online for alternatives, they seems somehow wrong. For example, I went here and clicked the "as in admit" tab...
but everything seemed to have the wrong flavor, e.g. legalistic or psychological. Would you expect to see "Angie reveals things about Brad," or "Angie discloses things about Brad"? "Spill" is a funny thought, short for "spilling the beans" I guess; it seems to belong to dialog in a Broadway musical, like "dishing the dirt."
The only word that seems at all plausible is "Angie talks about Brad," but still, that's not quite it. Can you suggest some standard English words for "revealing other people's secrets" at various points on the spectrum from praise to censure?
