It's nearly impossible to keep a secret when you're in the public eye.
Still, these celebrity moms were able to pull it off. In fact, they're so good at keeping a secret, they were actually able to keep the news of their own babies under wraps. For a little while, at least.
Take a look below to find out which moms were able to keep the ultimate secret from the media!
