"Wait, so how old is she?": Kris Jenner grills Scott Disick about GF Sofia Richie's age

And she can't even say her name...

Keeping Up with the Kardashians is all about family drama so obviously, as executive producer, Kris Jenner isn't going to shy away from asking the tough questions while the cameras are rolling.

In a sneak peek of this week's KUWTK the Kardashian-Jenner matriarch/momager extraordinaire sat at a kitchen table and zeroed in on her sorta ex-son-in-law Scott Disick and his May-December romance with a much, much, (MUCH!) younger Sofia Richie.

"What's going on? Are you dating?" Kris asks pointedly and an apprehensive Scott answers, "Sure."

"Are you dating one person? Just one?" Kris digs (yassssssssss drama!!) to which Kourtney Kardashian's ex replies, "Yeah. It's something new."

Kris continues prodding Scott and asks, "Are you going steady?"

Kinda uncomfortable Scott says, "I guess that's what the kids are calling it."

Kris then mouths 'Sofia' and Scott confirms, "I mean, I guess you know who it is."

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? Because I really don't know. Is she Kylie's age? 20?"

"19," Scott says.

"And you're 32?" Kris asks. "Four," Scott says.

Kris, not oblivious to the fact that she and the late Robert Kardashian had a huge age gap, starts comparing stats.

"You're 34? OK, so I was 17 and Robert was 12 years older," Kris reflects about her first marriage.

"You were underage, she's not," Scott states. "Touché!" Kris says with a twinkle is her eye.
