It's been just four months since Kim Kardashian and Kanye West welcomed son Saint, but the reality star revealed the rapper is already talking about expanding their brood!

"Kanye has been mentioning it every single day lately for the past 10 days," the 35-year-old said on Wednesday's Kocktails With Khloé series finale, sounding far less enthused than her hubby.

Khloé Kardashian suggested surrogacy as an option given that Kim struggled with preeclampsia during both of her pregnancies.

Kanye also discussed what it was like to move in with his mother-in-law Kris Jenner after the birth of their now two-year-old daughter North.

"It went from being by myself to being with Kim to her being pregnant and us living with her mom, and I was like, 'God I know you have a plan. This is for a reason,'" the 38-year-old hilariously admitted.
