And if you weren't already jealous of the Kardashian/Jenner Thailand vacation, you will be now!
Kendall Jenner posted one awesome video of her zip-lining through a Thailand jungle via Instagram on Thursday -- where she's giving her sister Kim Kardashian a run for her money in the booty department.

The 18-year-old captioned the candid clip, "this was fun."
Judging from the video, it definitely seemed like the aspiring model was a little bit nervous. But, after sis Kylie Jenner told her that her "ass looks good," Kendall gave it a go.
