Kendall Jenner always takes advantage of her birthday falling shortly after Halloween, throwing dress-up parties on Halloween weekend, a few days out from her actual big day, November 3rd. This year was no exception. On Sunday night, the model hosted a party on a West Hollywood rooftop dressed as Martian Girl from Tim Burton’s Mars Attacks! film. For her costume, Jenner wore a swirling red bodysuit from California-based brand L.A. Roxx and Maisie Wilen paired with a blonde beehive wig that stood over a foot tall. 

There to celebrate alongside her were Justin and Hailey Bieber, who came as a French maid, Kim Kardashian, Doja Cat, French Montana, and The Weeknd, who, never one to shy away from a dress-up party, came as Vito Corleone from The Godfather.

The classic Kardashian black and white photo booth also made an appearance with the slogan, Kenny’s Spooky Halloween 2021 plastered in the top left-hand corner. 

Of course, when you’re a Kardashian-Jenner, you don’t have just one birthday celebration. On Wednesday night, Jenner spent her 26th birthday having an intimate dinner with her family, friends and boyfriend Devin Booker.

On Instagram, Bieber shared a photo of her longtime friend blowing out the candles on a white cake, writing over top, “Birthday lady @kendalljenner we love you.”

Kourtney Kardashian also shared snippets from the evening, posting a short video and photo of the dining table to her Instagram Stories, showing the long table decorated with an old-fashioned white tablecloth with yellow floral designs, and several plant and flower displays. Kardashian’s new fiancé, Travis Barker, was also invited to the evening, with the drummer’s name tag clearly insight on the table. 

For her more low-key celebration, the birthday girl wore a brown turtleneck and wore her brunette hair loose. Though she hasn’t yet shared any posts from the evening, Jenner’s family made sure to mark her special day, with all of her sisters sharing tributes, as well as Booker posting cute couple photos to Instagram. In the first shot, Jenner can be seen sitting at a dinner table, over which Booker wrote, “Most beautiful woman.” The next image shows the pair both wearing hoodies with Booker’s arms around Jenner. He captioned it simply with the lock emoji.

It appears Booker has the family tick of approval too with Kim Kardashian, who missed the birthday celebrations due to being in New York (and on another date with Pete Davidson) now following the NBA-player on Instagram.
