The starlet posted a picture of the two gals from when they were very young, wearing glasses with big noses and mustaches! Kim wrote that the picture makes her laugh every single time she sees it, and we can see why! Too cute.
Kim wrote a nice note about her older sis on her blog: "Happy birthday to the best big sister in the world! We’ve been through so much together and I love you so much!! Thank you for always being there for me. You’re an amazing sister and an even more amazing mother to Mason."
