Ivana Trump has a new boyfriend: Michael Kennedy, a dapper French art dealer in his late 50s. A source said they met while dining at separate tables at the Plaza Athenee here three months ago. While Ivana is still technically married to her estranged fourth husband, Rossano Rubicondi, pals say “she is really very happy.” The new man is not to be confused with the Michael Kennedy who represented Trump in her 1990 divorce from Donald Trump. Ivana’s rep declined to comment.
