It was Khloe's first appearance since she announced her own pregnancy in December, but the Keeping Up With The Kardashians star kept didn't say if her sister is also pregnant.
Ellen tried her best to get a confirmation, asking,
Is Kylie craving yet? She's pregnant.
I don't know what you're talking about. Come on Ellen!
When Ellen asked why Kylie was not in the Kardashian Christmas card, she said,
I don't know, you've got to ask Kylie. Why don't you get Kylie on the show?
Khloe, who is six months pregnant with her first child, spoke about her own bump, though. When asked if she knew the sex, to which she responded: "Not yet", but the soon-to-be mom revealed that the couple want to find out.
Yeah. There's too many surprises in this whole thing that I'm definitely going to know.
She also revealed she and her boyfriend Tristan Thompson have already started thinking about baby names.
Adding she may follow the Kardashian initial trend, Khloe said,
I think if it's a boy I'll go with Tristan Junior. For a girl I don't even know where to begin. I think I'll go with a K or a T.
As to why she chose to announce her news on Instagram, Khloe told Ellen:
I just wanted to do something myself and write something that was heartfelt from me. I've wanted to have a baby for so long and it's just the perfect timing. God always has his plan and I just want to do it on my time and when I felt comfortable to do so.
Khloe revealed that she has experienced some sickness at the start of her pregnancy, saying,
At the beginning, the first trimester is the worst, and no one knows you're pregnant yet and you feel the most uncomfortable. Hopefully I look pregnant and not just fat, so people realise if I don't feel well or tired.
