John F. Kennedy Jr.'s family and friends opened up about his complicated five-year romance with Daryl Hannah in the new CNN documentary American Prince. "His mom did have concerns with Daryl Hannah, the movie star," Kennedy biographer Dr. Joseph Ponterotto revealed in the episode airing Saturday, August 9. "It was once said, to love John, you need the approval of his mom first." John Jr. and Hannah, now 64, reportedly originally met on vacation in Saint Martin in the early 1980s, with the two going on to have a highly publicized and often tumultuous relationship starting in 1988.
