Scott Disick allegedly found himself paralyzed with fear at the thought of possibly having gotten another woman pregnant while working in Arizona.

According to HollywoodLife, Star magazine reports the father of Kourtney Kardashian's three young children "hooked up" with the mystery woman back in January after meeting her at a Scottsdale nightclub he visited as part of a public appearance requirement.

"Scott slept with her," a source alleged. "She was really proud of herself for sleeping with him. She told everyone at work about it."

By the next morning, the 32-year Disick had apparently come to his senses, texting the woman to inquire if she was on the pill.

"He was totally freaking out," the source added.

Still, HollywoodLife reports the woman claims the next time Disick was in town, the two again spent time together and once more were intimate.

Disick and Kardashian have had their problems over the years, many of them seemingly sparked by widespread rumors of his infidelity. Earlier this year, reports even surfaced that he and Kourtney's younger sister, Khloe, have been "hooking up for years."

"When they hooked up, [Khloe] was going through a tough time with Lamar [Odom] and Kourtney had kicked Scott out," a source said. "One night, they bonded over their shared misery. They were drinking and one thing led to another."

According to HollywoodLife, In Touch magazine previously reported that this came on the heels of rumors he has also been intimate with Kendall Jenner and once even promised her he would leave Kourtney so that the two of them could wed.

"She will never forgive her sisters completely," the source said of Kourtney. "Khloe was her best friend. So Kourtney might not talk to her for years."

However, the sisters continue to be close, signaling that these rumors were likely false.
