(Almost) All of Khloé Kardashian's Sisters Sent Her Sweet Birthday Messages on Their Apps

It's Khloé Kardashian's 33rd birthday today. After a big weekend bash in celebration of the occasion, some of Kardashian's sisters took to their apps to wish the reality star a great day.

In honor of Khloé, big sis Kourtney Kardashian called her the "definition of #bodygoals," and reminisced about some of the times she's looked "smoking hot."

Kim Kardashian West, on the other hand, posted a sweet message thanking Khloé for being such an amazing aunt to her kids, North and Saint West.

"Happy birthday, Khloé! I'm so proud to call you my sister! You are one of the strongest, most determined people I know, and I love going through life together," she wrote. "Thanks for being my best friend and the best Auntie Koko to my babies!"

Khloé's little sister Kendall Jenner also made an app announcement, but hers included a joke.

"Happy birthday, Khloé! I hope you have the best 21st birthday yet, lol," Jenner wrote. "I love you!"

While Khloé's youngest sister Kylie Jenner didn't post a birthday wish on her app for Khloé (at least not yet!), she did make sure to come to Khloé's adorable surprise party over the weekend, and that's what counts.
