Kim and husband Kanye made a decision to use a surrogate for baby number three, after suffering scary complications with Saint's pregnancy.
"So I said to my sisters, 'Would I be really creepy if I get someone to dress up as a stork and drop the baby off at the front door and have to explain that?' Isn't that what we had when we were growing up".
"At the baby shower, I was like, 'I just want everyone to write a name on a little tile and see if there is something that sticks, '" she told Ellen.
She also discussed the family's progress on baby names (nothing is decided yet), how Saint feels about getting a baby sister, and how concerned she is about North adjusting to sharing her parents with a second girl.
But we still aren't any closer to a confirmation from either sister - and their sister Kim isn't going to let it slip.
"You know, it is really different", Kardashian West told Entertainment Tonight.
Appearing on U.S. chat show Ellen, Kim accidentally revealed that she's expecting another girl. But Kim said, "My daughter thinks she's tricky".
"People brought toys and gifts, and [North] was opening them all up the next day", she said.
When Star West came up, Kim revealed that had been Norths suggestion, but the mom 'was not vibing on it'. "She's really excited about that", Kim said.
But Kim did explain what she's looking for in a name. "She names everything Star West".
Since Kim's not down with Star, what do you think the new Kardashian will be called?
