It was a relatively quiet weekend for baby news -- until today, when Grammy award-winning artist Carrie Underwood announced that she and husband Mike Fisher are expecting. This will be the couple's first child.

The country star shared the news via an adorable Instagram photo of her pups Ace and Penny wearing t-shirts that read, "I'm going to be a big brother" and "I'm going to be a big sister." For the caption, she wrote, "In honor of 'Labor' Day, Ace & Penny would like to make an announcement. Their parents couldn't be happier..."

Though Underwood, 31, isn't due until this spring, her hockey star husband is already mulling over baby names. "We haven't picked names yet but it's looking like Fly is gonna fly. #boyorgirl #flyfisher," he tweeted earlier today. (Side note: Good thing they have some time to nail down baby's name!)

Congratulations, Carrie and Mike!
