Mason and Penelope better make room for a baby brother or sister! A little less than two years after Kourtney last gave birth, she and Scott Disick are now reportedly expecting their third child.
First a Kardashian wedding - then a baby! Kourtney Kardashianis now the sister with something huge to celebrate, as a new report claims that she and longtime boyfriend Scott Disickare expecting baby No. 3!
That's right - Kourtney is pregnant again, according to Us Weekly.
"She is only a few months along," a source told the magazine of the 35-year-old mom-to-be. Kourtney gave birth to her son Mason in December 2009, and then Penelope in July 2012 - but even though it's her third pregnancy, it may not be her last: "[Kourtney] wants to have a handful of kids," the source said. She's certainly well on her way!
The baby reportedly was planned, and as of now Kourtney and Scott aren't worried about whether it's a girl or a boy. "They don't know the gender yet," said a source. "They just want the baby to be healthy."
There have allegedly been a few recent hints that Kourtney is expecting. After returning to New York City following her sister Kim Kardashian's European wedding, an eyewitness revealed that the reality star appeared to have flush, glowing cheeks, Us reports. And even more telling - when Kourtney and Scott went on their NYC double date with Khloe Kardashian and French Montana, the mom-to-be reportedly abstained from drinking and opted for ginger ale instead.
HollywoodLife.com has reached out to Kourtney's rep for comment.
Congratulations, Kourtney! Between Kim's wedding and this, the Kardashians certainly have a lot to be thankful for right now!
