What JFK Jr. Thought of His Hair, 'Sexiest Man Alive' Title & Having Kids: His Assistant Tells All

Seventeen years ago, JFK Jr. passed away when the small plane he was piloting crashed en route to Martha's Vineyard, also killing his wife Carolyn Bessette-Kennedy and her older sister Lauren Bessette.

JFK Jr. had lived practically every day of his life in the public eye, but there is a lot that people still don't know about him. JFK Jr.'s good friend and former assistant RoseMarie Terenzio joined “Extra's” Mario Lopez at Universal Studios to talk about the man once considered America's prince.

RoseMarie pointed out there were two pivotal images "that made America fall in love with him,” the first being his childhood salute to his slain father. She added, “I think the 'Sexiest Man Alive' [cover of] People magazine was like the other turning point for him, and they fell in love with him all over again.”

As for his reaction to being called sexy by People, she shared, “He took it in stride. He really did. I think the most surprising thing to John was the fact that after he got married, the media intensified.”

The media frenzy focused on when the beautiful couple would have children. Terenzio revealed it was certainly something the couple discussed. “They did. They definitely wanted to have kids.”

Many also questioned if the lawyer and George magazine creator would ever follow in his famous father's footsteps. She commented, “He talked about it, yeah. I think eventually he would have run for governor of New York.”

After writing her 2012 book, “Fairy Tale Interrupted,” interviewing everyone from Cindy Crawford to Robert De Niro, Terenzio decided to do a documentary on JFK Jr.'s life. She explained, “Honestly, it was because, well, one, if you knew you were gonna be gone at 38, you wouldn't want to be forgotten, but more importantly, it was the guys [and] the director, Derik Murray; they were so amazingly respectful and wanted to honor him and wanting a real tribute, so it was an easy yes.”

Mario admitted he was a huge fan of JFK Jr. and his perfect hair. RoseMarie responded with the shocking revelation that “he hated his hair… He was constantly putting stuff in it to hold it down. That's why he always wore hats, 'cause he hated his hair.”
