Carrie Underwood shocked the world via Twitter on Tuesday that she and husband Mike Fisher welcomed their little boy into the world this past week.

"Tiny hands and tiny feet," the new mom tweeted. "God has blessed us with an amazing gift! Isaiah Michael Fisher born February 27."

I had no idea, but couldn't be more happy. They were so happy to start a family. Congrats and welcome to the world Isaiah.
