“It’s definitely serious. No one thought their relationship would last this long, but Kourtney is very happy,” an insider said.
Meanwhile, Kourtney’s former partner Scott – who is now in a relationship with 19-year-old Sofia Richie – “screamed at the top of his lungs” when he found out his former flame had moved on with someone new.
Kourtney said previously: “Last night I went to dinner with a guy and was photographed and I just felt like I should give Scott a heads up out of respect, even though he hasn’t done the same to me in the past. But the photos never ended up coming out in the end so it was pretty much all for nothing.”
And her sister Khloe Kardashian, who had witnessed the phone call, added: “He was screaming at the top of his lungs.”
