She better hurry up, as she's not getting any younger!

Kourtney Kardashian took son Reign to the doctor's office yesterday, right as a teaser for this Sunday's episode of Keeping Up with the Kardashians was released, which shows Kim talking about Kourt and ex Scott Disick having more kids together! We wonder what the mother-of-three thinks about this?

"So Scott just texts me that he wants to have another baby with Kourtney. I think he just wants one more, and she wants one more," Kimmy K tells pall Larsa Pippen in the clip.

"I mean, it’s like, Scott has a girlfriend, Kourtney has a boyfriend — we get it. They don’t even have to have sex. It could be IVF. I have to tell the rest of the family to be like, ‘Guys, should we encourage this?’ How cute will that be? They have to have another baby!" she continued.

“If she’s going to have another baby, why don’t they just have one together even if they’re not together? I think that I do hold onto this hope of Kourtney and Scott, just because I’m so used to them being together," she added.

We doubt LD's girlfriend Sofia Richie and Kourt's new 20-year-old boo Luka Sabbat are cool with this plan!
