NeNe Leakes and Kim Zolciak will make each other squirm on live TV ... forced to come clean about some very personal issues.
Production sources tell us NeNe and Kim have agreed to play Andy Cohen's game, "Plead the 5th" ... where they're asked 3 questions and they can only plead the 5th to one.
Andy typically asks the questions, but this time the girls will grill each other.
Six years ago, NeNe openly talked about Kim having a sugar daddy and cheating on her man, triggering an iconic club house showdown ... after Kim called in to confront NeNe.
We're told NO questions are off-limits. That and a few drinks should make it interesting.
