In fact, Conor, 18, bears a striking resemblance to a young John F. Kennedy Jr., seen here at the age of 19. With messy dark hair and a furrowed brow, their likeness is unmistakeable.
In this snapshot, John Jr. – the son of Jacqueline and John F. Kennedy – is seen in 1980 enjoying Labor Day weekend on Cape Cod, at the Kennedy family’s six-acre waterfront property in Hyannis Port, Mass. (JFK. Jr. died in a tragic 1999 plane crash, when he was 38.)
He also seems to be the spitting image of John F. Kennedy himself during a recent sailing outing with Swift, who makes an nice Jackie Kennedy. Notice the resemblance between them now and John and Jackie from a July 1953 Life magazine cover?
As for Swift and Conor’s relationship, the 22-year-old singer couldn’t be happier, according to a source.
“They have been dating for a bit,” the source tells PEOPLE. “She is swept off her feet.”
