After Kourtney Kardashian and Scott Disick were snapped together with the kids, here comes the rumor that the "KUWTK" star is pregnant with her fourth child.

According to Life & Style magazine, Kourtney Kardashian let her guard down and the unexpected happened, and now she's allegedly pregnant just six months after giving birth to Reign.

The article claimed, "It happened during a rare moment when Scott was being charming. But now the thought of having another child with him is giving her a panic attack. It was right after photos of Scott with another woman came out that Kourtney realized she'd missed her period."

The tabloid also claimed that Scott Disick doesn't know yet that Kourtney Kardashian is pregnant.

"She's completely stunned. She's definitely not 'down' with having Scott as her baby daddy anymore," the insider added. "Kourtney wants their relationship to end, not to have another reason to have to deal with him."

The rumor about Kourtney Kardashian being pregnant came on the heels of the photos published on Hollywood Life showing the "KUWTK" star reuniting with Scott Disick as they took their kids, Mason, 5, Penelope, 3, and 6-month-old Reign, to lunch in Los Angeles, California.

"Despite the reports of Kourtney refusing to communicate with Scott on any matter, the two were spotted going out to lunch with their kids in LA at the Beverly Hills Hotel in the afternoon," Hollywood Life said. "This lunch outing in Beverly Hills wasn't the first time Scott saw his kids after he recently returned to Southern California."

Life & Style reported that Kourtney Kardashian will fight for full custody of the kids, citing Scott Disick's irresponsible behavior and cheating ways.

The insider claimed, "Her team of lawyers has been notified. She knows she and her kids deserve better."

The tabloid also claimed that "KUWTK" matriarch Kris Jenner, ever the businesswoman, saw the opportunity to exploit the situation.

"Kris is having the crew film Kourtney, Khloé and Kim's reactions to Scott at every step. She knows viewers love a good catastrophe," the article added.
