The Kardashian Family Welcomes New Addition - Kourtney's Third Baby!

Congratulations to Kourtney Kardashian and Scott Dissick! The latest offshoot of the Kardashian clan is a baby boy. Here’s a fun fact for you – Baby Boy Kardashian II was born exactly 5 years after his elder brother Mason Dash. The little bro has his birthday on the very same day, in fact – December 14.

Happy birthday to the coolest little boy in the entire world. You teach me so much every single day… http://t.co/KVDO9cIoqU

The baby also joins big sis Penelope Scotland, 2.

Kardashian, 35, revealed she was having a boy on last week’s episode of Kourtney and Khloé Take the Hamptons on E! It all fits perfectly within Kourtney’s family, plan. Annoncing the sex of her baby, she said: “It’s going to be perfect for our family,” she said.

And in case you’re worried that little Mason now has both the holidays and his baby bro’s birthday to compete with, don’t be. This year, he still got a rather special special birthday celebration. His famous family, including aunts Khloé Kardashian and Kendall Jenner, threw him an early Nightmare Before Christmas-themed bash in November.
