Kourtney Kardashian and Scott Disick welcomed their third child together, a baby boy, on Sunday, December 14 ... according to E!
The two are already the proud parents of daughter Penelope, 2, and Mason, who actually turns 5 today. That's right, both Mason and the couple's newborn share the same birthday!
Kourtney revealed the baby's gender on a recent episode of "Kourtney & Khloe Take the Hamptons," with Mason breaking the news to the family -- watch the video below:
"I wanted a girl," Mason admitted after the reveal.
However, Khloe Kardashian was able to quickly change his attitude by pointing out, "Girls don't like aliens and Lego guys. When you have a brother you can say 'Look at all my Lego guys, brother.' You get to be rough and you can boss him around because you're the older one."
That seemed to do the trick.
Kourtney really embraced her third pregnancy, recently showing off her bare body in a new photo shoot for Dujour magazine.
"To me, nudity is not something to be ashamed of," she told the mag. "I'm at my best when I'm pregnant. It's such an amazing feeling, the transformation that your body goes through. There's something about that that's so empowering and beautiful, and I just really embrace it."
Congratulations to the happy family on their new addition!
