Between paparazzi snapping photos of them and journalists divulging their dirt, big Hollywood stars don't have many places to hide, especially when they're pregnant. But some of them are surprisingly good at keeping their lives low-key, like the following who had babies in secret.

Kylie Jenner is known for sharing so much of her life on reality TV, so she shocked us all in 2018 when she revealed that she had successfully hidden her pregnancy with her daughter Stormi from the public. Rumors had been running rampant that she was hiding a baby bump, but no one was able to confirm the theory that she was expecting rapper Travis Scott's child until three days after she'd given birth. On February 4, she tweeted,

"I'm sorry for keeping you all in the dark through all the assumptions [...] I appreciate my friends and especially my family for helping me make this special moment as private as we could."

Jenner's Instagram announcement revealing the little one's name broke the record for the most-liked photo on the platform, unsurprising considering how she had been keeping us on the edge of our seats for so long. Her mother Kris Jenner couldn't even fathom the fact that nobody had slipped the news for nine months. On an episode of Keeping Up with the Kardashians that aired shortly after, she said,

"Can you believe that Kylie got out of the hospital with not one report?"

Little Stormi is certainly not a secret anymore, as we've all seen her sweet face countless times on Instagram.
