Kim made the comments in an interview with ELLE magazine in which she told expectant mums to cover up under a 'huge blanket'.
But after being criticised for her quip, Kim took to Twitter to insist there had been a misunderstanding.
She hit back:
I guess you can't be sarcastic when doing interviews! I was asked about tips on pregnancy style.....
I jokingly said pregnant woman should hide/stay in if they looked like I did lol. I said ask Kourt her tips bc she has the best preg style
I really should start video taping the interviews I do & post on my website so u can see the laughs & how it's really said
Kim's Twitter rant came after she offered some hard-earned wisdom on maternity style during the interview with sisters Kourtney and Khloe.
When asked about pregnancy style tips Kim replied: "I recommend hiding for a good year and having no pregnancy style...that's what I recommend.
"If you can do it, hide. Never leave the house."
Her little sister Khloe chipped in, saying: "Okay, well that's not practical. Give a different answer."
Kim replied: "That's really my recommendation. Wear a huge blanket."
Kim gained more than three stone while she was pregnant with North and last year revealed that criticism about her weight gain really upset her.
