Kylie Jenner celebrated turning 29 with a “Princess Kitty” party filled with hot pink outfits, feather boas, tiaras and three elaborate birthday cakes.
The Kylie Cosmetics founder held the early birthday celebration at her Beverly Hills home on August 8, two days before her August 10 birthday. She first teased it as her “pre-bday princess kitty party” on Instagram Stories before sharing a fuller carousel from the night.
“Happy bday eve to meeee,” Kylie wrote in the post, describing it as her “dream princess kitty bday night” and saying her heart was full.
Her sisters Kim Kardashian, Khloé Kardashian and Kendall Jenner joined friends including Hailey Bieber, Devon Lee Carlson and Victoria Villarroel. Justin Bieber was also among the guests, while Kylie’s boyfriend Timothée Chalamet did not appear in the publicly shared party photos.

Kylie committed fully to the dress code in a hot pink latex halter minidress with matching nails, a feather boa, a crown and fluffy Gucci sandals. Vogue reported that the guests followed her lead. Hailey wore a sparkly pink spaghetti-strap top with cream capri pants, a feather boa and tiara, while Devon and Sydney Carlson, Khloé, Victoria Villarroel and Kelsey Calemine all incorporated different shades of pink.
Hailey also spent part of the evening mixing drinks. Footage from the party showed her working a cocktail shaker, with one drink jokingly labeled “The @haileybieber special.”
Kendall appeared in Kylie’s carousel kissing her younger sister on the cheek, while group photographs captured Kim, Khloé, Hailey and several of Kylie’s friends together. Kylie also drank from a jeweled cup that matched the maximalist décor.
Kylie Had Three Birthday Cakes, Including a Pink Bikini Torso
The desserts followed the theme just as closely. Vogue reported that cake artist Cory Pohlman created the detailed cakes for the celebration. The most unusual was sculpted in the shape of a woman’s torso wearing a pink string bikini decorated with “meow” lettering.
Another cake was covered in white icing and multicolored jewel-like decorations, while the third was a smaller pink design featuring four cartoon cats and the message “Happy Birthday Kitty Kylie.” “My friends got me the cutest cakes,” Kylie wrote while sharing the desserts. Pohlman has previously created elaborate cakes for Hailey Bieber, Lady Gaga and members of the Kardashian-Jenner family.
Justin Bieber, the Kardashians and Kylie’s Friends Joined the Party
Kim, Khloé and Kendall all appeared in the birthday carousel, along with Hailey, Devon Lee Carlson and Victoria Villarroel. Just Jared’s arrival and departure coverage also documented Justin Bieber at the celebration.
Khloé was photographed leaving with daughter True Thompson in the car, while her ex Tristan Thompson was seen driving away separately. Devon and Sydney Carlson shared a car with Kelsey Calemine and Devon’s fiancé, actor Duke Nicholson. Kylie’s daughter Stormi Webster was also reported to have attended.
Timothée Chalamet Was Not Shown in the Party Photos
Kylie’s boyfriend Timothée Chalamet did not appear in the photographs or videos publicly shared from the “Princess Kitty” celebration. Vogue specifically reported that it was unclear whether Chalamet attended, and People likewise said his attendance was unknown.
They have been together for more than three years. People reported shortly before Kylie’s birthday that the pair remain together and are not rushing toward an engagement.
Last Year’s Birthday Was a Much Quieter Affair
Kylie took a different approach when she turned 28 in August 2025. Kendall organized an intimate outdoor dinner that included a paint-and-sip activity, with guests creating artwork inspired by Kylie’s viral “Rise and Shine” moment.
Hailey and Justin Bieber were among the guests at that celebration as well. Vogue noted that Kylie spent her 27th birthday in the Bahamas with a smaller group that included Chalamet.
