When it comes to the Kardashian / Jenner sisters, there's absolutely no doubting that Kendall is the most enigmatic.

Admittedly quite shy, 21-year-old Kendall doesn't tend to share as much as her siblings either online or through interview, so we were fairly stunned that she decided to take part in Spill Your Guts or Fill Your Guts.

The notorious Late Late Show segment is James Corden's method of getting his guests to reveal as much as possible, and in fairness to Kendall she actually played ball… for the most part.

While she decided to drink bird saliva rather reveal who her least favourite member of Taylor's squad is, the model did admit that when it comes to her nieces and nephew's names, she definitely has a least favourite.

Oh, and when it came to ratting Kylie out? Kris actually INSISTED her daughter down some clam juice and stay loyal to the Kardashian family values…

Fair play, Kendall.
