Kourtney Kardashian has not opened up about Scott Disick and Sofia Richie’s relationship in public, but this does not mean that she hasn’t shared her thoughts with her closest friend.

A source told People that Kardashian was also surprised by Disick and Richie’s age gap when she found out that they were officially together. “The initial reaction from Kourtney when she found out that Scott was dating Sofia was not positive. Like most people, she thinks Sofia is way too young for him and doesn’t get it,” the source said.

But even though Disick and Richie have a 15-year age gap, Kardashian also acknowledged the fact that the supermodel has been a good influence on her ex-boyfriend. “He has very much shaped up in the past few months. Kourtney is happy Scott is doing better. Things between Kourtney and Scott are civil,” the source said.

After learning that Disick and Richie are dating, Kardashian predicted that the couple’s relationship won’t last that long. On Sunday’s episode of “Keeping Up With the Kardashians,” Kris Jenner admitted that she was surprised to know that Disick’s relationship with Richie is actually more serious than she thought.

Kardashian also never thought that she would allow Richie to meet her and Disick’s three children, but since they have been dating for months, the reality TV star agreed with Disick’s request to introduce Mason, 8, Penelope, 5, and Reign, 3, to Richie.

“For a while, the kids did not see their dad on a regular basis. It was very sad because they missed Scott. Now, he sees his kids every day,” the source said.

Also on Sunday’s episode of “KUWTK,” Jenner and Kim Kardashian already gave Disick their blessing to date Richie – not that it was necessary. The momager reminded Disick that he could tell her anything because she will always be like her mom.

Disick said that he’s grateful for the Jenner’s love and support especially since she also prioritizes him even when she has a lot of kids to take care of herself.
