Robert F. Kennedy Jr. once kept a list of up to 43 rumored mistresses in his cellphone. The Kennedy scion, now 70, had contact information for dozens of women in an alphabetical list under the letter “G,” which his late second wife believed stood for “goomar,” the Italian slang for mistress, The Post revealed in 2014. One of the women on the list was “Curb Your Enthusiasm” actress Cheryl Hines, who married Kennedy at his family compound in Hyannis Port that year.
