Confused about which Kardashian sister is the oldest? You asked, we answer!

The oldest of the daughters born to Kris Jenner and the late Robert Kardashian is 33-year-old Kourtney Kardashian, who was born on April 18, 1979.

That’s 28-year-old Khloe, with a birthdate of June 27, 1984. But the real youngin’ of the Kardashian family is Kris’s only son, 25-year-old Robert Kardashian Jr., who was born on March 17, 1987.
