Not true, NDAs are a popular thing in America, especially in showbiz. So many break ups end in an NDA, this hasn’t. She can say what she wants. If she repeats the claims then JD can’t sue injury to his reputation because everything from the trial is all out in the open now.
If he didn’t care about the money, why did a man heavily in debt from his various vices and alleged theft from former business partners spend something silly like $26 million on two cases, one which he lost and the other he gained only $1 million from an insurance company, not even Amber. On top of that he hasn’t got a gag order on her. It doesn’t seem like a win to me. And his truth is quite shaky - there were inconsistencies with what he said, news after the trial wasn’t favourable and a whole host of DV and IPV experts who deal with those things daily said they support Amber. He still will get work because men are never truly cancelled no matter what they do, but this is a massive hit to him financially and personally.
