Carrie Underwood Pregnant With Baby No. 2

Country music superstar Carrie Underwood and her Canadian husband Mike Fisher are adding to their family.

Underwood announced Thursday she is pregnant with their second child.

"Mike and Isaiah and I are absolutely over the moon and excited to be adding a little fish to our pond," the singer shared, in a video. "This has been a dream come true with the album and baby news and all that stuff."

Underwood said fans now know why her Cry Pretty Tour 360 doesn't kick off until next May. It will stop in Vancouver, Edmonton, Saskatoon, Winnipeg, Toronto, and Ottawa.

"We are just so excited and just so glad that you guys can share in this with us and be a part of this with us."

Underwood, 35, welcomed son Isaiah in 2015. She and Fisher, 38, were married in 2010.
