While Kim Kardashian might be the only Kardashian/Jenner actually commenting on these pregnancy reports, it seems Kourtney Kardashian might've referenced Kylie's impending news much earlier – yet everyone missed it.
Just one day before the news was announced, Kourt posted a picture of her and Khloé hugging Kylie, captioned with a super sweet note of support.
The caption reads:
"In life, you realize there is a role for everyone you meet. Some will test you, some will use you, some will love you, and some will teach you. But the ones who are truly important are the ones who bring out the best in you. They are the rare and amazing people who remind you why it's worth it. -Unknown"
So basically: during hard times, your loved ones will be there for you.
Maybe the post was Kourtney's way of telling Kylie she's got her back through this pregnancy.
