Kourtney Kardashian Scott Disick Secret: Couple Allegedly Splitting Up As Scott Rumored To Be Involved In Some 'Shady' Business Deals!

Kourtney Kardashian discovered what fans call a "shocking" secret of Scott Disick in the latest episode of "Keeping Up With The Kardashians."

How Scott can afford his expensive lifestyle has always been a mystery to fans of the show. The father of Kourtney's three children has been known to wear designer clothes, adorn himself in expensive accessories and drive sports cars.

But on the March 29 episode of the show, a series of events happen that prodded Kourtney's sisters to start questioning Scott's moneymaking ways.

First, Khloe noticed a stack of license plates in Scott's car. Then she saw several very expensive cars being delivered to Scott's home.

Their mother, Kris Jenner, also overheard  a conversation between Scott and a mystery caller that involved a $100,000 wire transfer.

"He was wiring money from one account to another," she reported to daughters Khloe and Kim Kardashian during that episode. "I overheard the whole thing happening."

"What kind of business is he doing where all these wire transfers are happening?" Kris continued.

But Kourtney appeared undisturbed by the whole mystery surrounding Scott and his business deals. In the same episode, Khloe confronted Kourtney about Scott's shady dealings and the latter gave an answer that showed she had no idea what the husband of her kids is up to.

"I feel like he's just putting together deals, like brokering things," Kourtney said. "I feel like he loves to buy cars."

Towards the end of the episode, Kris Jenner found out that Scott was actually acting as the president of a car company situated in Calabasas, unbeknownst to the whole Kardashian family. When Kourtney finally decides to ask Scott about this, he remains evasive.

"It's really nobody's business," Scott said. Kourtney then decided to take a step back and let Scott run his business the way he wants to.

Accordiing to a source of Hollywood Life, the couple are actually on the brink of a break-up.  "Kourtney's standing by Scott, but their relationship is hanging by a thread," the source reportedly said. "Scott isn't any better - he's not taking his sobriety seriously at all"

"It's heartbreaking for her because she can see how much pain he's in, but it's getting to the point where she doesn't know how much more she can take," the source continued.
