I don't see any signs of resentment or bad blood from the two families that reported those conversations.
The one family is just taking care of BL's daugter and I don't think they have an axe to grind. The other family were the winners in a custody battle and get child support from BL. They have 3 great kids from the deal. I don't think they would say something not true about the dad of those kids to the newspapers, I am sure the whole family knew the situation.
In family law, the parties to a case are often some of the angriest people, and sometimes more dangerous than any other kind of party to a case. Criminal defendants are the nicest people to deal with. Family law malpractice rates are some of the highest, family law attorneys run the greatest risk of getting murdered of all the lawyers out there, by their clients or opposing parties and family law attorneys experience the most stress of any other attorney, due to the anger, passion and anguish of their clients.
Every day that I am in Court, like today, I see people screaming in the halls, crying, wailing, fighting and at least once each time I spend over a few hours there, I see Sheriff's having to surround, arrest or escort someone out of the courthouse.
I have seen assualts, once in the parking lot.
Family law litigants are the most unglued of any litigants.
The only time I see parties involved in a family law case that did not have bad blood between are in simple cases with short hearings. Anytime you see protracted litigation that lasts weeks, months or years, you will see deep seated animosity. This can be a very nasty business, believe me!
ETA, whether true or not true, reporting bad things about the parent of the children entrusted to your care to the MEDIA, is bad for the children, not in their best interests. Why say such a thing to the media? Why not contact LE instead? The fact that they have does tarnish their credibility to some degree, for me. I need to hear more.
Finally, some people just like to get involved in a high profile case and/or distance themselves from people connected to such cases by bad mouthing them.
