Kourtney Kardashian Gives Birth To Baby Boy

The Kardashian-Jenner family just got bigger. Kourtney Kardashian welcomed her third child with longtime partner Scott Disick on Sunday, People reports.

The couple’s baby boy arrived on the same day as older brother Mason’s fifth birthday. Since Kourtney and Scott were obviously a little busy, Aunt Kim was on birthday party duty. But the biggest question? Will the new baby call Kris Jenner “grandma”?

Happy Birthday to the lego master Mason!!! You are so big I can’t take it! You are my everything!!!!! I love you so much!!!!
