While sources have said that both Kylie and her boyfriend of five months, Travis Scott, have told friends the news, the famous Kardashian-Jenner family has been expertly dodging the media - neither confirming or denying the pregnancy.
When asked outright, mum Kris Jenner told both fashion week reporters and Ryan Seacrest that the beauty mogul wasn't confirming anything.
Her father, Caitlyn Jenner, however, didn't get the secrecy memo, confirming that Kylie is most definitely pregnant.
"All I can tell you is that it [Caitlyn being told] was some time ago," the Olympian's rep told The Sun.
Yesterday Kylie posted a cryptic photo to Instagram showing off her tummy, however, it was too hard to tell whether she had a baby bump or not.
Now, with the news confirmed, we're sure it won't be too long before she debuts her bump for real.
