Kylie's older sister Khloe has also wished the reality TV star a happy birthday online, sharing a collage of images of them together with the message, "Happy birthday to my sister, spirit animal, partner in crime and best friend! @kyliejenner you constantly amaze me with your wisdom, maturity, sensitive soul, confidence....
