Celine Dion doesn't just have one of the most beautiful voices in the world, she also is a philanthropist!
The March Of Dimes, the Partnership for Maternal Newborn and Child Health, Save the Children and the World Health Organization have all teamed up to save the lives of preemies everywhere.
You can go to facebook.com/WorldPrematurityDay to write about or post a pic of a child, or a person who's child was born prematurely.
They want to show on a world map how premature birth effects everyone, everywhere!
