Mason Disick is keeping it up with his aunts, Khloe Kardashian and Kylie Jenner.

Kylie took the Instagram photo and wrote: “Hi everyone!! I just wanted to share some pics from this last week with you guys! I am soooo happy that my sister Khloe is home!! We had a family dinner together the second she got home and I took this pic of us with Mason. How cute is he!?”

Mason is quickly growing up in front of all the reality show fans.

Donning an all-pink attire for Easter, Mason went on his first Easter Egg hunt.  “My favorite thing was just seeing how excited Mason was,” Kourtney says. “He was obsessed with the Easter egg hunt — it was his first one. Just seeing how excited he got for the baskets that the Easter bunny left made it so much more special for us.”

Pretty soon, this little tot will be a big brother, as mom Kourtney is due late May.

Congratulations to the growing Kardashian-Disick family!
