Everything That Happened At Kylie Jenner's Star-Studded 21st Birthday Party

The Kardashians stepped out last night for Kylie Jenner's 21st birthday party, and the night was just as extra as you'd expect.

From Kylie's eye-catching outfit changes, to Kendall Jenner's barely-there dress, the Kardashian-Jenner clan proved once again that they know how to throw a party. Kris Jenner even got a little emosh giving the birthday speech for her youngest daughter, and Caitlyn Jenner reunited with the family to celebrate the momentous occasion.
