Caitlyn Jenner and Kris Jenner have a heated argument on this Sunday's I Am Cait.
While Kris is spending time with Caitlyn and her squad in New Orleans, they start to talk about Caitlyn's transition.
When asked if Caitlyn told her about being transgender "early on" in their relationship, Kris says "no."
"Oh I did too!" Caitlyn insists.
"She keeps saying she told me but she didn't do it," Kris says. "What happened was a conversation in a driveway, he says to me, 'Do you ever want to have more kids?' And I said, 'Oh God no.' So he says, 'Oh either do I, that's like, that's great! And I couldn't have any more kids if I wanted to.'"
Kris then reveals, "And he goes, 'Oh jeez you know back in the '80s I messed around with this or that and it kind of screwed up my sperm count but whatever.'"
She then tells everyone at the table she thought it might've been "steroids" because "he was an athlete."
Kris also claims, "He never said it was estrogen, he never said anything, he just said, 'I took some s--t in the '80s.'"
She then explains, "There was no, 'I am transgender.'"
But Caitlyn disagrees and says she told Kris she "had a condition that I've been dealing with forever" and said "I was on hormones" which is why it "might be tough to get pregnant."
Kris then reveals her friends told her to "have a bottle of wine and go have great sex."
They did and shortly after Kendall Jenner and Kylie Jenner were conceived!
