10. The Affair With Joan Rivers
At some point in their history together, Johnny and Joan Rivers shared more than airtime. In her autobiography, Rivers mentioned that the two had an affair while Joan was still married to her then-husband, Edgar Rosenberg. According to Rivers, it wasn’t the only time she went out on her husband. Edgar eventually ended his own life, which may say more about how much Rivers could impact someone’s life. Perhaps Carson’s cold shoulder to her was more personal than professional. Since they are all gone now, one can only speculate.
