The reality TV star is a week away from finding out whether she and the rapper are going to be parents to a baby girl or boy and she accepts that as soon as they know for sure, West will start planning the child's wardrobe.
And even though sister Kourtney is offering her kids' second hand clothes, Kim insists that won't be necessary.
She says, ""He (West) has a few key pieces, but if anyone knows Kanye they just know how into fashion he is and I think he's gonna have things, like, specially made. I don't think hand-me-downs are gonna work.""
Appearing on U.S. chat show Jimmy Kimmel Live! on Tuesday night (29Jan13), the socialite revealed the baby was a ""nice surprise"", explaining she and Kanye had talked about starting a family but didn't expect to start it so soon.
And Kardashian had another surprise last month (Dec12) when West decided to announce the baby news onstage at a gig in New Jersey.
She recalls, ""I was like, 'Is he really saying what I think he's saying?' I was so confused... He is so excited; it's really cute how excited he is.""
