Kylie Jenner's ex best friend is Jordyn Woods.
Jordyn Woods and Kylie Jenner were close friends for many years, but their friendship ended in 2019 after Jordyn was involved in a scandal with Tristan Thompson, Khloe Kardashian's then-boyfriend.
The incident led to a public feud between the two families, and Jordyn and Kylie have not been seen together publicly since.
