The moment didn't go over well with Kourtney's sister, Kendall Jenner, who slammed Richie, 19, on social media.
Responding to a Disick follower who posted one of the photos of Disick, Richie, and his kids by Kourtney, Mason, 8, Penelope, 5, and Reign, 3, Kendall wrote in a major diss, "Awww Scott and his kids."
Kendall's followers seemed to love the shade, calling the model "The Shady Queen" and "The Savage Queen" in response.
Disick, 34, and teen model Richie went public with their romance in September, although they were seen together as far back as May. They've flaunted their love as a duo, but it was only on Saturday that Richie finally was seen out with Disick's three kids that he had in a tumultuous long-term unmarried relationship with Kourtney.
Bizarrely, Richie is closer in age to the two older Disick children than she is to their father! After her bitter split from Disick, Kourtney has looked askance at his galpals. On an episode of Keeping up with the Kardashians, Kourtney, 38, referred to "The Lord's" recent love conquests as "hookers."
The on-camera takedown didn't shock fans as the age difference between Disick and Richie has raised also eyebrows. Still, Kendall and Kourtney's sister Kylie started dating quite young and is now pregnant by rapper boyfriend Travis Scott. Pregnant Kylie is just 20 years old.
