Kourtney Kardashian got so much love from her famous fam on her 36th birthday on Saturday! Khloé Kardashian penned her a heartfelt handwritten message inside a card and Kim Kardashian, who, as we know, loves selfies, shared on Instagram one of her and Kourt, in addition to her own sweet well-wishes. In addition, mom Kris Jenner posted a sweet childhood photo with her message. Khloé, 30, had signed the card using her nickname, KoKo. She called Kourtney, a mother of three, the “best, finest, grooviest, most on fleek, badass, MILF, bootyliscious sister in the world.”
