They grow up so fast! When we first met the Kardashians, they were all wild, young things taking over Miami and New York and the Hamptons. Over a decade later, they’re still constantly jet-setting and going on fabulous vacations and filming it all for their reality show, Keeping Up with the Kardashians, but these days they’re doing it all as moms. With the exception of Kendall Jenner, all the sisters now have kids of their own, and those kids are becoming young adults right before our very eyes. Recently, Khloé Kardashian shared a picture with her nephew Mason Disick, sister Kourtney Kardashian‘s eldest, and he looks seriously grown up. Check out the video above to see just how much Mason has grown. 

Can you believe that? It feels like just yesterday that the first Kardashian grandkid was learning how to walk and talk, and now he’s already eight years old. In just a few months, on the December 14th birthday he shares with little brother Reign Disick, he’ll be nine. Can you believe that there’s family member almost as old as the Kardashians’ empire itself? And the older he gets, the more he looks like his dad.

I think I will call him… me

Scott and Mason have been spending some quality time together lately, too. It’s nice to see that the father of three still has time for his soon-to-be teenage kids even though he’s frequently off gallivanting with his currently-teenage girlfriend. Just the other day, Lord Disick even shared a hilarious video of him and Mason have a father-son moment that involved hair gel and a spot-on Adam Sandler impression. Scott also called his first born his “mini me” in an Instagram caption, writing, “You complete me.” How cute is that? It won’t be too long before Mason’s all grown up and is his dad’s mini-me for real. Until then, though, we’ll just enjoy all his cute pictures with Auntie Koko and the rest of the fam.
