The Keeping Up With The Kardashians star and baby daddy Scott Disick welcomed a son in Los Angeles, according to a report, but have not released any information on their new bundle of joy.
On a recent episode of Kourtney & Khloe Take The Hamptons, Kardashian revealed the gender of their baby. "I'm so happy we're having a boy. It's going to be perfect for our family."
Although she was busy giving birth, Kardashian did take the time to Instagram a photo of Mason. "Happy birthday to the coolest little boy in the entire world. You teach me so much every single day and changed my universe the second I met you," she wrote.
"You have taught me what life is all about and I am truly blessed and honored to be your mommy."
Kardashian and Disick also have a daughter together, Penelope, 2.
