Caroline Kennedy was sworn in today as the U.S. Ambassador to Japan, but all eyes were on her son, who bears a striking resemblance to the late John F. Kennedy Jr.

John "Jack" Schlossberg, 20, stood by his mother's side as she was administered an oath by Secretary of State John Kerry.

The handsome college student, who was 6-years-old when his uncle died in a plane crash, may not have the Kennedy last name, but he has clearly inherited the winsome genes.

As one person on Twitter put it: "When did Caroline Kennedy's son become such a 10?"
