Carrie Underwood and husband Mike Fisher welcome new baby boy!

Country singer and former* American Idol* winner, Carrie Underwood, and her hawt hubby Mike Fisher have just welcomed a baby boy, Isaiah, into the world. Woooooohooooo! Caz has waited five days to announce it since giving birth on Friday 27th February, but what better way than on the social medium of Twitter huh?

Just how cute are those little hands! Eeeeeee! Carrie told ABC earlier this year that her and Mike decided to find out the sex of their bubba during a big envelope reveal at a private dinner: "Just the two of us in a nicer setting, but we both knew. So, that was just confirming our suspicions. We didn't really speak of it before, 'cause we were both just like 'Whatever. It's all good.' But we knew it was a boy."

Mystic Meg could well be out of a job, by the looks of it. Congrats guys!
