Kendall & Kylie Jenner have a 'secret' model cousin who is stunning

The Kardashian's are one good looking family. 

But it seems that the good looks aren't just limited to the famous ones, but the extended family members as well. 

A "secret" cousin has come out of the woodworks and Kendall Jenner has serious modelling competition!

Natalie Zettel is Kris Jenner's 18-year-old niece and the first cousin of Kendall, Kylie, Kim, Kourtney, Khloé, and Rob.

Her last name may not be Kardashian, but we're still gonna be keeping up with her!
