Scott Disick Posts Adorable Video of Penelope & Mason

Scott Disick likes letting his kids let loose. The father of three had some quality time with his two eldest this Sunday. Mason and Penelope are many years away from joining their dad at the club, so he brought the dance club to him. With Demi Lovato's "Cool for the Summer" blasting from his Mercedes speakers, they rocked out. Penelope looked excited by the chance to bust a movie with her big brother, but Mason was all business. He came to head-bang (in a Yeezus tour shirt, of course) and that's what he did. Disick captured the moment for Instagram, captioning the video, "Best thing ever." Reign, at only seven months, missed the dance session. Disick and Kourtney Kardashian announced their break-up last month.
