It's a celebration! Kendall Jenner stunned in a sparkly outfit that showed plenty of skin while celebrating her 21st birthday in a SUPER expensive dress.
The beauty stepped out in a $9,000 barely-there outfit as she headed to hot spot L.A. hot spot Delilah.
And check out the back!
Not to be outdone, Kylie stepped out in leather pants and a mesh top that revealed her cleavage.
Khloe, who has been MIA from Kardashian events recently, after skipping Kanye West's concerts in California, wore a black minidress and Kourtney also joined in on the fun.
Kris looked excited as she also dressed in all black, which seemed to be the color of the night.
Hey, Caitlyn! Jenner hopefully didn't have an awkward run-in with Kris at the bash.
Scott Disick may no longer be with Kourtney, but that didn't stop him from supporting Kendell! What are your thoughts on her bash? Let us know in the comments section.
