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. khloekardashian/Instagram "Happy birthday, Khloé!
