This is not a joke, people! 

Carrie Underwood and Mike Fisher adorably announced on Labor Day that they are expecting their first baby!

They posted this photo with their dogs, also known as their fur babies, wearing tees that say they're getting "promoted" to big brother and big sister.

We could not be happier for this wonderful couple and their beautiful family! 

Can't wait to see some pics of the baby bump, and of course, the baby!
