Khloé Kardashian also joined in on the birthday love, sharing a heartfelt tribute to her big sister on Instagram.

"Happy Birthday to my sister, my best friend, my forever twin flame in chaos and greatness, @kimkardashian where you go, I go," she began her post.

Khloé continued, "Every year, I'm in awe of how you continue to evolve. Somehow, you keep leveling up in strength, grace, wisdom, and heart. You've always been powerful, but lately it feels like you've tapped into an even deeper layer of yourself, calmer yet more unstoppable, grounded yet still dreaming bigger than ever."
