It's hard enough trying to keep a pregnancy under wraps, but when you're a celebrity it's nearly impossible. Some go the Beyonce route, and proudly flaunt their baby bump on national television, while some prefer to keep their bumps away from the paparazzi--that is, until someone accidentally (or purposefully) spills the beans.
For example, take what happened to Angelina Jolie when she was pregnant with twins Knox and Vivienne. On a promo tour for "Kung Fu Panda," her funnyman co-star Jack Black let Jolie's pregnancy news slip at the 2008 Cannes Film Festival. How did that happen, you ask? Well, you see, it was an honest mistake.
And just last week, proud grandpa Rod Stewart innocently revealed the name of his first grandchild--Kimberly Stewart and Benicio Del Toro's newborn daughter Delilah.
While it's hard to imagine getting mad at an elated grandfather for sharing his joy with the world, sometimes even the media will stop at nothing to reveal a celebrity's most hidden secret.
Here are some examples of more celebrities who have had their baby secrets spilled.
