Kylie 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 is 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.”
