Kourtney Kardashian 'unfazed' by Scott Disick's new girlfriend

Scott Disick, the ex long-time partner of Kourtney Kardashian posted a photo of himself and of his new girlfriend, Lindsay Vrckovnik while in a hotel room in Miami, E Online reports. The photo was quickly deleted from his account but the photo still floats on the internet.

Disick, 32, has been spotted regularly with Vrckovnik, 18, who is a model. According to Yahoo, Kardashian is "unfazed" by the blossoming relationship of the two.

"Kourtney surprisingly isn't fazed by this at all. She's moving on. She knows it's just a fling," a source told the outlet.

"She's trying hard to ignore it and just focus on the kids," the source added. "She knows they'll never get back together."

The news of Disick's relationship with the 18-year-old model reportedly broke out last week when they were seen having a night out at a bar in NYC. They went to a night club, a house party and then returned to Disick's hotel room at 6 am.

As for Kardashian's reaction, the reality TV star reportedly laughed when she found out about the model's young age. The report by Daily Mail inferred that Kardashian saw Disick as "insecure" because he is hanging out with such a young girl.

"She thinks Scott believes he looks cool dating a young model, which is a bit of a cliché for a wealthy man approaching their mid-30s. It's a move Kourtney thinks he's making to show off to his Hollywood pals," the source explained.

According to ET Online, Disick and Kardashian are clearly not together anymore and never will be. The two have three children together, Mason, 5, Penelope, 4, and nine-month-old Reign. As to how Disick does his daddy duties, a source disclosed that he can see the children "whenever he wants to."

"Despite all of Scott's addiction problems, he is a great dad and loves those kids with all his heart, and they are obsessed with him. He comes to her house to see them," a source close to the two told ET. [But] Kourtney is not taking Scott back—never, as of right now. "Kourtney has been through a lot of drama with Scott over the years but it's for real this time."

The break-up issue will reportedly be televised in the 10th season of "Keeping Up with the Kardashians" on Sunday on the E! Channel.
