Inside Kylie Jenner’s 29th Birthday Bash With Hailey Bieber & More

Best Believe Kylie Jenner is Bejeweled as She Celebrates Her 29th BirthdayKylie Jenner’s birthday is off to a purr-fect start. Though the Khy founder turns 29 on Aug. 10, she kicked off the celebrations early with a star-studded soirée boasting a princess kitty theme. “Happy bday eve to meeee,” Kylie captioned an Aug. 9 Instagram post featuring photos from the party, “i had my dream princess kitty bday night my heart if so full i love my life and my friends.” In one photo, The Kardashians star posed alongside her guests—including pal Hailey Bieber as well as sisters Kendall Jenner and Kim Kardashian—as they all donned pink outfits complete with matching boas and princess crowns. For the occasion, Kylie wore a pink latex mini dress and feathered kitten heels. To complete her princess-inspired look, the Kylie Cosmetics founder wore a pink crown and matching boa. Kylie—mom to Stormi, 8, and Aire, 4, with ex Travis Scott—also played into the kitty theme with one of her two birthday cakes. Indeed, she shared a snap of a pink cake that featured icing art of four cats snuggling close together, reading, “Happy Birthday Kitty Kylie.”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 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.”Kylie Jenner/InstagramAnd 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.” Keep reading for a look back at Kylie through the years..Donato Sardella/WireImage2008Kylie attends Matrix at A Time for Heroes Celebrity Carnival just months before the Keeping up with the Kardashians series premiere.
