After touching briefly upon her own pregnancy cravings, Ellen slyly asked if Kylie had any.
"What do you mean?" Khloe asks, playing dumb.
"She's pregnant," Ellen replies.
"Oh, I don't know what you're taking about," Khloe says, laughing.
Degeneres then tries to press further, asking why Kylie wasn’t on the family Christmas card this year.
"Um, I don't know. You gotta ask Kylie," Khloe says. "Why don't you get Kylie on the show?"
After Ellen jokes that she could call Kylie and ask her about it, Khloe says she doesn’t know her number.
"She must be pregnant. There's too much secrecy around it," Ellen says. "Look at your eyes! Y'all, she's pregnant! I can tell by her eyes!"
"I am pregnant!" Khloe insists. "I am pregnant!"
"No, not you! Kylie is pregnant!" Ellen says. "I can tell Kylie is pregnant."
Ellen then tries to make a bet with Khloe over whether or not the youngest Kardashian is pregnant – but Khloe simply replies, "You just are so cute!"
"So, Kylie's pregnant. That's great," Ellen says in response. "Do you need help naming a baby?"
"That is the hardest. I mean, I think if it's a boy, I'll go with Junior, but I don't know what to do: Tristan, Jr.!" Khloe replies, clearly relieved not be talking about Kylie anymore. "For a girl, I don't even know where to begin. I think I want a K or a T."
As for why she waited so long to reveal her pregnancy?
“I just wanted to do something myself and write something that was heartfelt for me," she says. "I’ve wanted to have a baby for so long it’s just the perfect timing. God always has a plan and I just wanted to do it on my time and when I felt comfortable to do so.”
