The Kardashian-Jenners greeted the supermodel on social media.
Kylie Jenner deemed her sister Kendall as her “partner in crime, my best friend!”
Khloe Kardashian noted that Kendall is “one of the most loyal, rare and gentle souls I've ever known.”
“Mommy” Kris Jenner wrote, “You will always be my little girl who all you wanted to do was ride your pony and grow up and be a supermodel!!!!!!!!”
Kourtney Kardashian did not make a lengthy tribute like her sisters, but only uploaded a photo showing herself and Kendall in 1998.
Kim Kardashian, meanwhile, took to Instagram and posted a picture of herself and Kendall taken at this year’s Met Ball, along with a heartfelt note.
Scott Disick, a longtime Kardashian-Jenner family member, posted a snap via Instagram Stories of him and the model, which he called “Killa Ken,” at an event.
Dad Caitlyn Jenner and brother Rob Kardashian skipped the social media greetings.
