Her big sister, Kim Kardashian, also wrote the most gorgeous message.
"Happy Birthday @khloekardashian I have never met anyone like you. Inside and out you are one of a kind and just flawless in my eyes. I’m so grateful to have a sister like you," Kim wrote. "I’m so happy we are so close and that our souls decided to take this trip down to earth around the same time! So lucky to have you in my life. I know this year is going to bring so much joy into your life!"
Kylie Jenner shared the most beautiful throwback with a touching message.
Kylie has so much love for her big sister and it shows. "Khloé, no time or distance apart could ruin the bond we have. I feel so lucky to call you my sister. Thank you for all the love, guidance, and laughter throughout the years," she captioned the pic. "My life truly wouldn’t be the same without you. I feel so blessed to take the journey of life together because there will just never be another you. Happy Birthday."
Kourtney shared a hilarious video of Khloé carrying her.
"To my soulmate sister who carries me through life literally, even barefoot on a dirty street. Just know that I will always have your back. I would choose you in any lifetime," she wrote. "Happy birthday, you deserve the world. Slob kabobs forever."
True was all dressed up for her mamá's big day.
The little one looked like a real-life princess in her big dress and tiara. We love how happy Khloé seems when she's with her daughter. She truly deserves that!
Khloé shared such a cute video of herself at her party.
The birthday girl looked absolutely gorgeous in a pink tube top, wearing her long blond hair in loose waves. True looks so cute in her mamá's arms.
Koko hit the dance floor and the little ones joined in, too.
Khloé wasted no time before hitting the dance floor and enjoying her birthday close to her friends and family; even Kylie's baby, Stormi, was dancing it up!
The birthday girl sure had some fun.
There was a mechanical bull in the middle of the party, so of course, Khloé went for a ride and she did it like a total pro.
Kylie was in charge of throwing the party, and she truly went all out.
Kylie hired the best of the best to throw her big sister the most incredible party. The floral arrangements were done by celebrity florist Jeff Leatham and event planner Mindy Weiss took care of the rest.
The decorations all over were so cute!
The decorations had Khloé's face all over them. They even recreated a pink gym, because the birthday girl loves working out so much. That's so thoughtful!
They had quotes that Khloé has said in the past.
How cute are these drinks? There were flowers hanging from the ceiling and every touch is so simple but beautiful.
