"Um, I don't know. You gotta ask Kylie," Khloe responds to the initial question. "Why don't you get Kylie on the show?"
"She must be pregnant. There's too much secrecy around it," Ellen replies. "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."
The pair also talked baby names, with Khloé revealing she will find out the baby's gender before they are born.
"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.! For a girl, I don't even know where to begin. I think I want a K or a T."
Later, Khloé spoke about her pregnancy cravings and revealed her mother, Kris Jenner, showed up to her house with eight boxes of Krispy Kremes.
The Keeping Up With The Kardashians star also gushed about Tristan's help during pregnancy.
"He's such a good dad, and he's so great even just during pregnancy," she says. "I think he makes me more excited, too. He's super protective over me, he's really a dream and I fell lucky."
As for marriage plans, she says "I hope so. I'm not in a rush for any of that. As you know, I've rushed quite a few things before, so right now I'm so loving the place I am in my life and I'm just very happy with how things are going."
