And first up is, of course, Momager Kris Jenner who has taken to Instagram with an emotional post.
Kris reposted Khlo's preg announcement pic and wrote:
Kardashian and Thompson are expected to give birth to their bb boy in early 2018.
Meanwhile, Kris' other daughter Kim Kardashian will welcome a new member to her fam in the coming weeks via surrogate.
And now we wait for Kylie Jenner to announce her pregnancy.
Any day now...
