Kendall is the 'It' model of this Jenner-ation. We can't believe that we've been watching her since the age of 12. We mean, we basically grew up with her and watched her grow into the full-blown superbabe she is today. In honor of her 21st birthday, here are just 15 times she partied without her ID. Cheers to her finally being legal!
