KUWTK star Scott Disick brought son Mason Dash Disick, 7, and daughter Penelope Scotland Disick, 4, to the grand opening of Sugar Factory American Brasserie in Las Vegas Saturday. Son Reign Aston Disick, 2, was MIA as was Scott’s on-again-off-again love, Kourtney Kardashian. The reality star and entrepreneur glared at photographers and seemed genuinely annoyed that they were taking photos of his kids. He was there in a professional capacity as he was hosting the event for the restaurant and candy shop. After his kids had passed through the pack of paps Scott took his place in front of the step-and-repeat. He followed the directions of the photographers as to where to turn, posing, but not smiling for pictures. In the past it’s been son Mason who has been outspoken when approached by paparazzi. He’s even been caught on film calling them “stupid” and “weird” and also aiming both a toy gun and making a gun with his fingers at the often overly aggressive photographers. But Mason was on his best behavior at Sugar Factory, leaving his dad to give the side eye all by himself.
