Scott Disick has allegedly reached out to Kourtney Kardashian and Travis Barker to congratulate them on their pregnancy.

But the Flip It Like Disick star, who has three kids with Kourtney and wants the best for the couple, worries that he won’t be able to control his own kids after she gives birth.

A source told Life & Style that Scott knows it’s “selfish” to think about himself right now, but he can’t help feeling insecure about his kids.

“Scott did text Kourtney to congratulate her, so he does want her to be happy,” a source said. “It’s just bittersweet for Scott because he feels like he’s losing a hold on his kids because of Kourtney’s new family.”

The source said that Scott “wasn’t upset” when he found out about her pregnancy and that he is actually happy for her.

But the founder of Talentless thinks that “his three kids will now put even more focus on the new baby and therefore their stepdad Travis. He knows it’s selfish, but he can’t help it,” the person said.

Us Weekly also got confirmation from another source that Scott called Kourtney and Travis to wish them well.

“Scott knows this is what Kourtney has wanted for a long time, and as bittersweet as it was, he reached out to congratulate her and Travis,” an insider said.

A source said that Scott will keep hoping that he and Kourtney will get back together one day, even though he knows that his hopes are not “realistic.” At the end of the day, he just wants Kourtney to be happy.

“Scott has come a long way from where he was when Kourtney and Travis first started dating,” the person said. “Most people know it was a tough realization for him to accept, and it took quite a while to get there.”
