The model/Kardashian family starlet was getting out of a car after it started rolling backwards, with the driver believed to have forgotten to put on the handbrake before getting out to escort Kendall into the building.
You can see the whole thing here:
Kendall was almost struck by the car door before noticing and quickly getting out of the way. She then stood in shock and watched the car roll back and crash into a post.
Kendall, 20, was on her way back to hotel after walking for Versace as part of the Milan Fashion Week.
