Prior to the party, Kim headed to Instagram to pay homage to her not-so-little girl in a touching post: "I just can't believe it was 20 years ago today I became your mom! Scared out of my mind yet so excited! Had I known how easy it would have been to raise you I certainly would of had a lot less anxiety! I'm extremely proud of the leader you are, the heart you have and share, the love you have for your siblings, the respect, loyalty, and commitment to your family and above it all how you always have remained TRUE to you!! Keep shining!!!"
