Scott Disick and Sofia Richie have been linked for almost a full year now, starting when they were spotted hanging out at Cannes last May. (They made things “Instagram official” in October.) And in an upcoming episode of Keeping Up With the Kardashians, momager Kris Jenner spares no questions as she grills Disick for all the details on his May-December (almost literally!) romance.

“What’s going on? Are you dating?” Jenner asks with a smile as Disick uncomfortably confirms that he is. Jenner then goes on to try to get him to open up about the relationship, asking — twice — if he’s only dating one person. He says he is and that it’s “something new,” though it’s unclear when the episode was filmed.

Jenner then whisper-asks if the “one person” he’s dating is Richie. Spoiler alert: It is!

“Wait, so how old is she?” Jenner asks. “Because I really don’t know. Is she Kylie’s age? 20?” Disick confirms that Richie is 19, and Jenner starts doing the math, mistakenly pointing out that he is 32 (he’s 34).

“Okay, so I was 17 and Robert [Kardashian] was 12 years older,” the momager recalls of her relationship with her late ex-husband, to which Disick replies, “You were underage, she’s not.” Jenner’s response? “Touché!”

Richie’s father, music legend Lionel Richie, previously joked to Us Weekly that he was “scared to death” of his daughter’s new relationship, but the Kardashian-Jenner family hasn’t previously publicly addressed the couple’s romance — unless you count what many saw as Kendall Jenner throwing some shade at the pair via social media. Either way, the tense convo between Jenner and Disick is one to watch for sure.

Keeping Up With The Kardashians airs on Sundays at 9pm ET on E!.
