A Complete Photo Diary of Kendall Jenner's 21st Birthday Party

How does an It girl/It model celebrate her 21st birthday? Let Kendall Jenner show you how it's done.

To start off the night on a (semi) low-key note, she and her closest friends had dinner at Catch LA in West Hollywood. She attended in a decked-out catsuit by Julien Macdonald (brave attire for eating a meal, but then again, this is a supermodel we're talking about).

They indulged in cocktails by Absolut Elyx and sushi before sitting down for a three-course meal that included crispy cauliflower, ribeye steak, parmesan-truffle fries and, of course, birthday cake. Kendall's parents, grandmother and sisters—yes, even Kim—were in attendance, along with her girl pals like Hailey Baldwin and Justine Skye, according to sources.

At the dinner, Scott Disick and the Catch owners (Mark Birnbaum and Eugene Remm) gifted her with a massive framed Marilyn Monroe print, which was a hat tip to the theme of the evening: Old Hollywood. The second half of the night took place at 1920's-themed restaurant Delilah (by the same owners of The Nice Guy).

The birthday girl, however, showed up in a very New-Hollywood-style LaBourjoisie dress covered in Swarovski crystals and worth an estimated $9,000.

There were about 50 people at the party, including Jenner's family, Harry Styles, A$AP Rocky, Cindy Crawford, Kaia Gerber and Gabrielle Union, sources say. Kanye West and Kim Kardashian were also present, but snuck in through a back entrance and the couple only stayed for about an hour. Even Givenchy's Riccardo Tisci was there.

And since it's not a true Kardashian birthday without a special performance, Travis Scott also performed three songs including "Antidote" for the small crowd. Kendall even DJ'ed a set herself.
