Lord Disick is not happy, y’all. Scott Disick is reportedly upset with his ex Kourtney Kardashian because she disallowed his teen girlfriend, Sofia Richie, from attending Kris Jenner’s recent Christmas Eve bash. According to Hollywood Life, Scott, 34, is furious that Kourt, 38, barred Sofia, 19, from the event — but brought her 24-year-old boyfriend, Younes Bendjima, as her plus-one.

“Sofia was hurt and bothered that Kourtney told Scott he couldn’t invite her to the family’s Christmas Eve party. She really felt ostracized and dissed by the entire family. When she voiced her frustration with Scott he completely understood where she was coming from and vowed to ‘make it up to her,’” an insider told the website. “He’s absolutely going to have a 1-on-1 sit-down with Kourtney to find out what the deal is with her disdain for Sofia and get to the root of her issues with her.”

The outlet reported that Scott was particularly unnerved with Kourtney — with whom he shares kids Mason, 8, Penelope, 5, and Reign, 3 — because he has apparently made a concerted effort to be cordial with Younes. “Scott was very respectful of Younes when he met him, and felt he handled the encounter with immense maturity,” the insider continued. “He definitely thinks Kourtney was being a hypocrite by bringing Younes to the party and slighting Sofia in the process — Scott wants the same respect that he gave to Younes to be reciprocated to Sofia.”

Though she isn’t ready to rub shoulders with Sofia just yet, a source recently told Life & Style that the mom-of-three believes Scott’s relationship with Nicole Richie’s little sister has made him a better father to their children. “Kourtney is giving Sofia credit for turning Scott into a better man, and more importantly, a better father,” an insider explained. “She’s happy that Scott’s priorities have shifted from nightmare party animal to reliable baby daddy.”
