Sharing a clip from the upcoming series of Keeping Up With The Kardashians on her Instagram, Kim was seen announcing the news.
Videotaping her sister Khloe, she said: “What happens every time I say ‘Guess what?'”
Khloe responded: “A person is pregnant.”
“We’re having a baby,” North West’s mum added.
It’s been reported for some time that Kim and her rapper husband are set to expand their family with the help of a surrogate.
In a recent teaser from the show, the 36 year old gave Scott Disick a tour of a nursery.

“I’ll be quite honest, I don’t even know what this room is,” the confused dad of three confessed.
When told it will be a nursery, he then asks: “Are you pregnant?”
Looking coy, the reality star replied: “Are you kidding?”
It’s been reported that Kim’s sister’s Khloe Kardashian and Kylie Jenner are also expecting babies.
TMZ announced that 20-year-old Lip Kit Queen Kylie is expecting a baby girl with boyfriend Travis Scott.
It was later reported that Khloe and her beau Tristan Thompson are expecting their first child together.
Neither has yet confirmed the rumours.
