Kim - who is around 12 weeks pregnant - said: "Of course I do want to know. I can't find out yet, but I do want to know.
"No preference, I just want a healthy baby."
The 32-year-old beauty admits she's been lucky with her pregnancy so far because she hasn't suffered from morning sickness and has been feeling good.
She told Us Weekly magazine: "I have felt good. I haven't had any morning sickness, but it still isn't the easiest. People always say it's easy and fun. It's definitely an adjustment learning about your body and stuff like that. I've been feeling really good so that's good."
However, Kim admits being pregnant isn't easy and was amazed how her sister Kourtney - who has children Mason, three, and six-month-old Penelope - seemed to breeze through her pregnancies.
She said: "Even my sister has made it look so easy and it's not as easy as people think. It's a little painful, there's a lot of growing pains. But I've heard it's all worth it so I'm looking forward to that."
Kanye - who has been dating Kim for eight months - shared the couple's happy news during a performance at Revedl in Atlantic City, New Jersey on December 30, telling the audience to "stop the music and make noise for my baby mama".
