Kris then recalled her first marriage to the late Robert Kardashian and told him: "You're 34?"
The 38-year-old has been dating the 24-year-old for nearly a year and Scott initially struggled to come to terms with the romance.
When Kris finally outright asks the father of three if he's dating model Sofia Richie, he coyly confesses, "I mean, I guess you know who it is". Addressing Kourtney Kardashian's ex, Jenner says: "Are you dating one person?"
Then Kris asks the question everybody has when the find out he's dating Nicole Richie's kid sister: "Wait, so how old is she?" Just one?" Kris digs (yassssssssss drama!) to which Kourtney Kardashian's ex replies, "Yeah.
"I guess that's what the kids are calling it", Scott said. Jenner asks. "Because I really don't know".
That's when Kris calls out the couple's 15-year age difference.
Scott and Sofia have traveled the world together throughout their short relationship, having been spotted in Miami, Aspen, Milan and most recently Mexico.
And Sofia Richie looked back in the swing of things as she walked through a gas station to fuel up her vehicle in Los Angeles on Friday afternoon. Is she Kylie's age?
Scott Disick and Sofia Richie have been linked for nearly a full year now, starting when they were spotted hanging out at Cannes last May.
