When Caroline Kennedy was sworn in as the US Ambassador to Japan, her son, John Schlossberg, was the one getting the attention.

The 20-year-old Yale student set hearts and Twitter ablaze, with many noting his striking resemblance to his late uncle, John F. Kennedy, Jr.

One person asked, "When did Caroline Kennedy's son become such a 10?"

From his striking jaw line to his thick, dark trademark Kennedy hair, he is well on his way to becoming one of the country’s most talked about eligible bachelors.

He’s not all about being handsome, though.

While pursuing his studies he’s opted to pile on additional learning and is seeking his certification to become an emergency medical technician.

A close friend of Jack’s – that’s the name John goes by – said, “Jack sees this training as a way to give back to the New Haven community that he’s living in, and where there’s obviously a lot of issues such as crime and poverty.”

His medical pursuits don’t mean politics is out of the question.

He’s already spent time working in Washington DC, serving as an intern for John Kerry, as well as being involved in local elections.
