By the time Carrie Underwood headlines at Bridgestone Arena in September of 2019, she'll have another "fish in the pond."

The country-music superstar, who is also, of course, married to former Preds Captain Mike Fisher, is not only bringing her Cry Pretty World Tour to Nashville next year, the couple is expecting their second child before the tour kicks off in May.

Underwood made the announcement with a video posted to her Instagram page on Wednesday morning, stating, "Mike and Isaiah and I are absolutely over the moon and excited to be adding another little fish to our pond."
