Kylie Jenner and Travis Scott – Baby Stormi

As both a social media and reality show superstar, everyone knows what Kylie Jenner is up to. So it was a real coup that she managed to hide an entire pregnancy throughout 2017. Of course, there was widespread speculation throughout that time that she was pregnant with boyfriend, rapper Travis Scott’s baby, but Kylie and her high-profile family and friends were completely mum. She gave birth to a baby girl, Stormi, on February 1. True to form, she made the announcement via an 11-minute YouTube video, which quite nearly broke the internet.
