Inside the Princess Kitty Birthday Fête
Kylie Jenner celebrated turning 29 by organizing an exclusive gathering that mandated a strict girl-world dress code, requiring attendees to sport toy tiaras and frothy pink feather boas, as reported by W Magazine. Held over the weekend as a candy-colored pre-game to her actual August 10 birthday, the event featured bubblegum latex attire, kitten heels, lower-back rhinestone tattoos, and mixed drinks served in diamante-adorned cups. The aesthetic leaned heavily into a mature, tongue-in-cheek interpretation of childhood nostalgia.

The guest list brought together a tight-knit circle of family members and friends. Attendees spotted arriving or featured in evening photographs included sisters Kendall Jenner, Kim Kardashian, and Khloé Kardashian, alongside close friends Hailey Bieber, Victoria Villarroel, and Sydney and Devon Lee Carlson. Other notable figures present included Justin Bieber, Duke Nicholson, and Tristan Thompson. Confectionery displays at the venue included a multi-colored gem-covered cake, a cat-themed cake reading “Happy Birthday Kitty Kylie,” and a torso-shaped creation featuring a buttercream bikini. Jenner’s daughter, Stormi, also joined in to sing “Happy Birthday” during the festivities.
