Kourtney Kardashian and Scott Disick welcomed their third child into the world on Sunday. The Keeping Up With the Kardashians and Kourtney and Khloe Take the Hamptons star gave birth to a baby boy December 14th–the same day son Mason Disick celebrated his fifth birthday.

“The family is freaking out with joy,” a source told E! News. “What an amazing coincidence.”

Kourtney Kardashian recently explained that she has taken time off following the births of each of her children.

“I’m not getting a baby nurse,” she told Fit Pregnancy magazine. Kardashian is featured on their December/January cover. “I take two months off and no one is allowed to bother me or talk to me about anything work-related—or maybe three months this time.”

Kourtney’s only real complaint throughout her third pregnancy was morning sickness–and the fact that it didn’t necessarily occur in the morning. In fact, she calls the term ‘morning sickness’ a misnomer, because “for me, it was even worse at night.”

Grandmother Kris Jenner and aunts Khloe and Kim Kardashian, along with Kylie and Kendall Jenner are no doubt thrilled about the birth of Kourtney and Scott’s newest addition to the family. It will be interesting to learn what Kourtney Kardashian names her new baby boy.

Congratulations to the entire Kardashian family on the birth of Kourtney and Scott’s new baby boy.
