Happy Birthday Kendall Jenner


Kendall Jenner turned 21 with a bang Wednesday night, with a whole bunch of celebs.

The party started at Catch in WeHo, then moved to Delilah nightclub and almost everyone was there ... Hailey Baldwin, Kylie Jenner, Madison Beer, Big Sean & Jhene Aiko, Will.I.Am, Travis Scott, Vic Mensa, Mr. Brainwash, Scott Disick, Chris Brown, Paris Hilton, Cindy Crawford & Kaya Gerber, Romee Strijd, Kris Jenner & Corey Gamble, Khloe & Kourtney Kardashian & Jonathan Cheban.

No Kim Kardashian sighting -- though it's possible she sneaked in a backdoor --
