It basically broke the internet after she announced the news, because the most shocking part was that Kylie was only 19-years-old.
Now, a video has resurfaced on a fan account, showing Kylie and her best friend Stassi Karanikolaou high-fiving about not becoming pregnant at 19.
"I'm not pregnant. Never was," Kylie says. They high-five and Kylie continues, "We did it. 19-years-old and we're still not pregnant."
In the video, you can see that Kylie has the same pink hair as this photo of her from October 2016, and she's wearing the same jumper as in the video.
In September 2017, rumours about Kylie's pregnancy were going wild online, however sources claim she was pregnant four months before then. Kylie turned 20 in August 2017, meaning she was likely 19-years-old when she found out that she was pregnant.
Fans were quick to point this out, with one writing, "But she was couple weeks later 🐸☕."
While it doesn't at all matter that Kylie was expecting a child at 19, it is just a funny video to look at now.
What's important is that Kylie and Travis are amazing parents to gorgeous little Stormi! Kylie only just told Vogue Australia that, "Creating life was one of the most beautiful moments in my life. It's hard to explain why, it's just when you experience it you understand."
