The "All I Want For Christmas Is You" singer's gift was a little belated, giving birth to twins Moroccan and Monroe in April 2011.

The "Paper Planes" rapper stunned at the 2009 Grammy's, not only for her performance, but because it fell on her actual due date. Her son, Ikhyd Edgar Arular Bronfman, was born the following day.
Beyonce
And of course, this list wouldn't be complete without Yonce's famous pregnancy announcement during her performance at the VMA's. That said, we might be seeing Queen Bey appear on this list again later this year - the "Love on Top" singer is still set to headline Coachella this spring, despite just having announced that she's pregnant with twins!
