Megyn Kelly Told NBC She'll Sign Confidentiality Agreement for $10 Million

Megyn Kelly has told NBC she will not spill whatever beans she has on the network and the people who work there ... but at a hefty price.

Sources familiar with the negotiations tell TMZ ... NBC offered Kelly $38 million, which the network says represents the balance owed on her contract. As we reported, Megyn was pulling in around $25 mil a year and she was one year and some change into the 3-year deal.

We're told NBC attached a pretty standard string ... a confidentiality agreement. Her lawyer said his client would sign on the dotted line ... for an additional $10 million. We're told NBC told the attorney to pound sand.

NBC definitely has cause for concern ... Kelly wrote a book, "Settle for More," in which she targeted Fox News Channel, and she has been critical of the network since her exit.

We're told settlement negotiations are ongoing.

The Daily Mail first reported the $10 million demand.
