NEW YORK (AP) -- Carrie Underwood is a new mom, and like all proud parents, she's showing him off in a photo.

The multiplatinum country singer gave birth to Isaiah Michael Fisher on Friday, and on Tuesday, she announced it to the world on Twitter. She posted a picture of Isaiah, showing his tiny hand and a bit of his mouth.

He is the first child for Underwood, 31, and her husband, Mike Fisher, who plays for the National Hockey League's Nashville Predators.
