Inside Kylie Jenner’s “Princess Kitty” Birthday Bash With Hailey Bieber, Kendall Jenner and More

The reality star also set out to make the whole place shimmer as she included multiple bedazzled elements into the party. 

Not only was a second cake with white frosting bespeckled with gems, but Kylie also showed off how she included the special touch on plastic cups at the party.

And while the themed décor was a standout from the birthday bash, it’s the people she spent it with that made the night so memorable. 

In one snap, Kylie flipped off the camera as her assistant-turned-BFF Victoria Villarroel danced beside her. In another pic, she got some sister love as Kendall hugged her from behind, placing a sweet kiss on Kylie’s cheek.

And in the post’s final video, Kylie smiled as she held daughter Stormi close by her side while her guests sang “Happy Birthday” in her honor.

Following what Kylie called her “pre bday” party on Instagram Stories one day earlier, the birthday love rolled in.

“Best night we love you so much birthday princesssss,” Kylie’s longtime friend Lauren Perez commented under the post, while Alex Consani quipped of Kylie’s zodiac sign, “Leo final boss.”

And Khloe Kardashian, of course, dedicated a whole Instagram post to her baby sister’s birthday, showing a closer look at her own pink Jean Paul Gaultier dress while also taking a sisterly jab at her youngest sibling.

“A little vintage JPG for a vintage KJ,” she wrote on Instagram Aug. 9. “You’re basically 30 now babe.”

And Kylie’s extravagant party is right on brand for the 29-year-old. After all, she called herself a “typical Leo” in a 2024 interview with British Vogue, noting that while she’s mellowed out in some ways, she was once “always the loudest and silliest in the room.”
