♡ It’s your birthday @kimkardashian!!! There are so many wonderful things I wish people knew about you. There are SO many things, so I will only name a few. For all the years of your life, you have glowed from the inside out. There has always been a magnetic energy about you. You’ve written your own set of rules, always with love. You have forever had an immense amount of courage and faith that everything will always work out. But most importantly, You leave people better. You want everyone to be the best version of themselves. You leave people feeling empowered and full. I pray, on your birthday and every day of your life, that you forever feel loved, respected and appreciated! We all love you so much! I am so proud of all that you were, all that you are and all that you are going to be! Happy birthday @kimkardashian!! You are everything to so many but especially me ♡

One clip showed Kim sprawled on a bathroom floor, before Khloe and their older sister Kourtney help her to the toilet where she vomits.

“You’ve got to throw up or you’re going to be really sick tomorrow,” they tell her.

Other snaps showed the Kardashians when they were little, and with their half-sisters Kylie and Kendall Jenner.
