The reality TV star is set to have her first child with rapper Kanye West in July, and will choose to find out whether it is a boy or a girl if it is revealed on a scan.

She told E! news: "I don't know what we're having yet. I do want to find out, I do."

The 32-year-old star would not say whether she prefers to have a boy or a girl, but added so far her growing bump has not interrupted her sleep patterns at all.

She explained: "I sleep amazing, it's like the best sleep ever. I'm a really easy sleeper though, you can put me on the couch with all these people in the room and say, 'You've got 10 minutes,' and I'll take an eight-minute nap."

Kardashian added her pregnancy is going so smoothly, she doesn't "feel anything, and I don't crave anything".

The star's mother, Kris Jenner, is preparing for the baby, but also biting her tongue and trying not to "gush" too much to Kardashian about it.

She said: "I think Kim's probably so sick of my advice by now, but what it does for me is it brings back memories from when I was pregnant with them.

"So she'll say something and I'll think, 'Oh my gosh, I remember back then,' and I'll try to share that. And, you know, I try not to gush too much because I can be annoying, I'm sure."
