Are Kendall and Kylie Kardashians or Jenners?
Legally and biologically, Kendall and Kylie share the last name Jenner from their father, Caitlyn Jenner. However, because they grew up alongside their Kardashian half-sisters under Kris Jenner's management and household, media outlets frequently lump them into the broader "Kardashian-Jenner" moniker.
What is the age gap between Kourtney and Kylie?
There is an 18-year age gap between the oldest sister, Kourtney, and the youngest sister, Kylie.
Why do people confuse the Kardashian and Jenner ages?
