And while we can anaylse her seemingly bumpy Instagram selfies 'til the cow's come home, we finally have confirmation from a very key family member that Kylie is pregnant!
"All I can tell you is that it was some time ago," the statement read.
Caitlyn, 67, is the first family member to address the baby claims.
According to a report from Hollywood Life, Caitlyn is said to be "shocked and disappointed" over the pregnancy.
"She thinks Kylie is way too young to have a baby, and that she should have waited until she was in a long term committed relationship," a source told the website.
"Obviously, Kylie has more than enough money to ensure that she can pay for help but Caitlyn still thinks that having a baby will take a huge toll on Kylie's life."
The insider continued: "Caitlyn is concerned that Kylie and Travis really haven't been dating very long, and that a baby will put a big strain on their relationship, but Kylie believes the opposite - that she and Travis will be together forever."
While Caitlyn was happy to comment on the news, it was a different story when E! heavyweight Ryan Seacrest messaged Keeping Up With The Kardashians star Kris Jenner during an appearance on Live With Kelly and Ryan.
After dropping the momager a text on air, Ryan revealed: "Kris says Kylie's not confirming anything. That's the news from the family this morning. Kylie is not confirming anything."
Meanwhile make-up mogul Kylie is yet to officially comment on her impending motherhood, instead dropping several clues on social media that she could be with child.

Most tellingly, she recently uploaded an illustration of her older self cradling her younger self with many believing she could be expecting a daughter.
The reality star has always insisted she's wanted to be a young mum, admitting to Elle UK: "I would love to have a family and build a home with a farm in Malibu Canyon and just have my kids and throw away my phone. Just really, like, live my life and not do this anymore."
Surely now Caitlyn has spoken out an official announcement is imminent!
