Dynastic Alliance

Which recently separated newspaper publisher has been seen regularly in the company of a woman from an even more famous dynasty? They're longstanding friends; she's still married; and she's too preoccupied with an illness in the family to think about the future. But that hasn't stopped the speculation. (Okay, so the newly separated newspaper publisher is pretty obvious: the New York Times' moose-loving Arthur Sulzberger. But the identity of his supposed lover is a surprise.)
