Kourtney Kardashian will do just about anything to help a family member in need. In the March 31 episode of Kourtney & Kim Take Miami, the 33-year-old mother of two asks her partner Scott Disick if he would support her offer to become a surrogate for her younger sister Khloe Kardashian.

(Earlier in the episode, 28-year-old Khloe told family members about her struggle to start a family with husband Lamar Odom. "I don't ovulate, and now my uterus lining isn't thick enough and I have to take pills to make my  uterus lining thicker," the X Factor co-host shared. "If that doesn't get thicker, then I cannot carry a baby.")

"You're telling me you want to get pregnant, carry a child and give it to Khloe?" Disick asks. "It would be her child with Lamar," Kourtney explains.

Disick can't seem to wrap his head around the idea of Kourtney carrying her sibling's child. "That's weird," he says. "Why wouldn't you adopt a kid in need?"

Counters Kourtney, "What if you want your own blood child?"

"You don't just go putting babies in other sisters because you can," Disick fires back. When Kourtney admits she doesn't know exactly how surrogacy works, Disick shouts, "This is not a normal conversation to come home with! It's too much for me. This is freaking me out!"

The ever-calm Kourtney decides to table the idea for a moment. "Nothing is happening," she reassures Disick. "I was just having a conversation."

Kourtney & Kim Take Miami airs Sunday, March 31, at 9 p.m. EST on the E! network.
