Despite Kardashian, 44, and Blink-182 drummer, Travis Barker, tying the knot in 2022, Disick reportedly hasn't come around to the couple kissing, hugging, and cozying up in public. 

"Scott takes being a dad seriously and wants what's best for the kids," a source at OK! Magazine alleged. "He's put his foot down on more and more issues lately, including asking Kourtney to tone down the PDA with Travis in front of their children."
