I believe that a good combination of the suggestions made by Mr. Love Machine and Mr. Damdonzi are in order here. A closing consult for Boat, with both you and Mrs. Lawyer, would put a resounding close to the situation for all involved. And by all means, please provide any correction to her posting as needed. Also, be sure to indicate to her that you feel compelled to make her new employer aware of her professional practices as a form of reference for her.
As for the Dingy, again, a meeting of the three of you is imperative. Inform her that you fully expect that anything said in the privacy of your own home remain private and since she is unable to comply, she is unable to remain in your employ. When the protesting begins, as it will, be sure to enlighten her to the manner in which her disclosures were used. Make her aware that that sort of disloyalty and disrespect will not be tolerated and that her services are no longer needed. And that her lack of good judgement are resulting in a lack of notice and severance on your part. Please don't forget to add that in light of the situation, you will absolutely not be able to give her a favorable reference for possible future employers.
After all, one good phkn deserves another. Or two, as the case may be.
