It doesn’t get cooler than this.
“Best thing ever,” the dad of three captioned an Instagram video Sunday of son Mason, 5, and daughter Penelope, 3, dancing to Demi Lovato‘s hit “Cool for the Summer” inside his car.
Disick, 32, seemed to suggest that he regrets the breakup earlier this month, posting an Instagram of his solo place card at a wedding with the caption “When you realize the grass isn’t always greener.”
The reality stars ended their relationship after Disick was photographed partying on vacation, and he kissed an unidentified woman in Las Vegas weeks later.
“He really screwed up, again, and the entire family knows all about it,” a source told PEOPLE.
