The Keeping Up With The Kardashians matriarch is preparing to become a grandmother for the fourth time – and she couldn't be happier!
Chatting on Australian radio show Kyle & Jackie O, the star said: "Isn't that exciting? Who would have thunk it! There is so much excitement, just one thing after another.
"Just when I thought we would settle down for five minutes, little miss Kourtney gets pregnant and we couldn't be more excited!"
Kourtney's baby news came just after sister Kim married Kanye West in a fairytale ceremony in Florence, Italy.
It will be Kourtney's third child. She and long-time boyfriend Scott Disick are already parents to son Mason, four, and daughter Penelope, one.
Kris said the mood in the Kardashian household couldn't be better right now after so much positivity in such a short space of time.
"Kourtney is over the moon, Kim and Kanye are ecstatic. Everything seems really good."
But, perhaps alluding to less happy headlines surrounded son Rob, she added: "We all have our stuff we go through from time to time and we do the best we can and get through it."
Rob was a noticeable absence at Kim's wedding, being pictured flying back to Los Angeles by himself on the day she exchanged vows in Italy. So far, there's been no word on what exactly happened, although Kris has said he's going through some things right now and she wants to be there for him.
