The fashion industry's "It" girl is officially a grown up!

Kendall Jenner enjoyed her 21st birthday by celebrating with a family dinner at Catch restaurant in Hollywood, followed by a wild party at Delilah nightclub. Khloe, Kourtney, Scott, Kylie, Tyga, Kris, and Caitlyn were all in attendance, the only person missing was Rob and his pregnant fiancee Blac Chyna. Oh, and rumored boyfriend A$AP Rocky!

Pals including Hailey Baldwin, Chris Brown, Travis Scott, Paris Hilton, Big Sean, and Will.i.Am also came out to toast the b-day girl, who looked stunning in a green fur and bodysuit before changing into a $9000 Swarovski crystal dress by designer Antoine Salameh.

Kim and Kanye arrived late night for a low key appearance, but managed to sneak into the club unnoticed. "They were very chill all night. Kim got on the mic at one point and said something funny and that was about it. She seemed pretty upbeat," a source dished to People.

So what did Kenny get as a gift? Oh no big deal, just a Rolls Royce! Life is good when you're rich, famous, and the legal drinking age!
