Scott and Kourtney have dated on and off since 2006. They share three kids together, Mason, 7, Penelope, 5, and Reign, 2, so it's no surprise that Kourtney is hurt by Scott's new relationship.

An insider told The Heat, "this relationship is certainly ruffling a lot of feathers, most of them Kourtney's." They added, "seeing Scott with Sofia has absolutely broken Kourtney, because it looks as though they're really in love." Disick recently referred to the 19-year-old model as "family."

"She hates the idea of Scott settling down with someone almost half her age — especially a famous model like Sofia," the insider continues. "As much as Kourtney has tried to move on from Scott, and even get revenge by dating younger men, she's still got feelings for him." The Keeping Up With The Kardashians star was currently linked to model, Younes Bendjima.

The insider added that, "the relationship has sent shock waves through the entire family." 20-year-old  recently discovered that she was expecting a baby with her boyfriend, Travis Scott. And now, her sister, Khloe Kardashian also has a bun-in-the-oven!
