Scott Disick met his 18-year-old girlfriend before splitting with Kourtney Kardashian

Chloe Bartoli may have been the fling that ended Kourtney Kardashian and Scott Disick's relationship, but his next romantic folly was already waiting in the wings.

According to Heat magazine, 32-year-old Scott's current girlfriend Lindsay Vrckovnik, 18, was already in the picture before Kourtney, 36, dumped him in July.

"He was still with Kourtney," Scott's friend and manager David Weintraub told Heat. "But it was during the downfall of their relationship, so it wasn't really like they were really together, together - but he did meet Lindsay before the actual, 100 percent official break-up."

Kourtney isn't going to like this. Radar Online has already reported that she's banned Scott from bringing Lindsay around their three children.

"She made it very clear to Scott that he is not to bring this girl around their kids," a source told Radar. "Those kids are already having a really tough time without their dad being there as it is, and Kourtney told him that the fact that he is even dating a barely legal girl is absolutely disgusting!"
