The reality star, who was reported to have made $17.8 million (£11 million) from her recent wedding to NBA player Kris Humphries, said that she feels ready to start her own family.
"It would be a dream that all three of us, even Kourtney again, were pregnant at the same time. That would be amazing," Kim told People.
"Hopefully soon. Being a mum is something I've always wanted so I would love to be one someday."
Kim added that nothing has changed about her relationship with Humphries since tying the knot, saying: "I love being a wife. It's really fun, but I don't feel any different. I still have that exciting dating feeling with him."
E! will air the couple's wedding as part of a four-hour special entitled Kim's Fairytale Wedding: A Kardashian Event this October.
