Kim revealed that she was pregnant again in a teaser following the mid-season finale of Keeping Up With The Kardashians.
Following a doctors appointment, Kim spilled the beans to her sister Khloe Kardashian.
Beaming from ear-to-ear, an excited Kim told Khloe: "I just got the blood test back, and I am pregnant!"
Kim, who spent Sunday night tweeting about the episode, did not reference her pregnancy. However, she earlier teased that she had some "exciting news" to share.
Both Kim and rapper husband Kanye have both previously discussed their desire to expand their family. They are already proud parents to daughter North West, who will turn two this month on 15 June.
Kim has previously spoken of the difficulties she has faced to get pregnant, with the reality star describing the process as "exhausting".
She recently told E! News: "You can't try harder than we try. It's getting exhausting. He always says 'Trying for baby No. 2 isn't as fun as trying for baby No. 1."
Congrats to Kim and Kanye!
