Kourtney Kardashian Pregnant With Baby Number 3, Sister Kim Kardashian Makes First Public Appearance Since North West Birth [VIDEO]

Kourtney Kardashian is reportedly expecting her third child with longtime boyfriend Scott Disick, who isn't too happy about the news of becoming a father yet again, according to Wetpaint.

"Kourtney has confessed she's expecting," said a source, according to Hello Magazine. "She's very excited and only telling a select few right now - but she just couldn't keep it quiet any longer."

"Kourtney has that kind of glow she had with Mason and Penelope," added the source. "They wanted to have one right after Penelope."

What sparked the rumor was when the reality couple went on a recent family trip to Miami where she blatantly avoided to drink any alcohol or eat any raw fish, which is typically unsafe from pregnant women to consume.

"Kourtney has confessed she is expecting. She is very excited and only telling a select few right now - but she just couldn't keep it quiet any longer," a source said.

The star, who has six siblings, has made no secret of the fact that she wants a large family.

"How many children do you think we could fit in this house?" Kourtney joked during an episode of Keeping up with the Kardashians. "In the playroom, I could build bunk beds for four."

Kourtney, 34, is already mother to Mason, three, and one-year-old Penelope. Meanwhile, her younger sister, Kim Kardashian gave birth to her first born, North West seven weeks ago. Kim made her first public appearance on Friday in a short clip on her mom's talk show, Kris, in which she said she is "loving life right now" and congratulated her mom on the show.

Kourtney Kardashian infamously shared the video footage of her giving birth to Mason on Keeping up with the Kardashians (watch below), leading some to believe she may do it again.
