Other sis Khloé Kardashian shared a similar Instagram photo collage featuring adorable pics of Kourt and Khloé together. "Happy birthday to my twin soul, my spirit animal, my ace, my MILF, my boo, my best friend," Khloe wrote in the caption. "I f--king love you so much! I could never explain how much I adore you.... You have to be around us to understand our bond. @kourtneykardash 35 never looked so good! Thank you for always being YOU!"
Rob Kardashian, who's usually pretty silent on social media, even took to Instagram to share B-day wishes. "Happy birthday to my little thangy thang @kourtneykardash ! June and John Cash .... Love you!!" he wrote with a flashback photo of him and Kourt.
Rob shared a second snapshot of him, Kourtney and Scott Disick, writing, "Lol good times and happy birthday to my wisest sister @kourtneykardash ! Goodness @letthelordbewithyou, u and I been doing the chips for a long time little Richards."
