While Kim has kept relatively quiet about the pregnancy news, she spoke with Ellen today about how her children are coping with the news.
As she discussed 4-year-old North's reaction to gaining a new sibling, the star accidentally revealed she is expecting another baby girl!
"I thought I really do want to have a baby shower, because I want her to feel that something's coming, and for her to really understand it," Kim said. "So people brought toys and gifts, and she was opening them all up the next day and she said: 'Mum, you know since baby sister is not here, I think I need all of her toys in my room, and I'll play with them and make sure they are all okay for baby sister'."
"She's a toy tester, and you just told us it's a girl," Ellen said to a stunned Kim.
The duo also played a hilarious name-the-baby game, which actually resulted in the pretty suggestion of "Elle West," which we definitely love!
Ellen also probed Kim for answers about her sisters hush-hush pregnancies. While Kylie Jenner and Khloé Kardashian have both been reported to be expecting, neither have confirmed (or denied) the news.
"When there are lots of rumours we have these family group chats, and we threaten each other's lives if we speak for the other one. We respect each other's right to speak for themselves, " Kim diplomatically replied. "Hopefully they can come on and address whatever rumours you might have."
