"You might be wondering or asking, 'Carrie why is your tour starting in May?' Well... yay! Mike and Isaiah and I are absolutely over the moon and excited to be adding another little fish to our pond. This has just been a dream come true with album, with baby news and all that stuff. We're just so excited and so glad you guys can share in this with us."

It's been quite a year for Underwood. At the end of 2017, the singer suffered a fall outside her home that resulted in a broken wrist and more than 40 stitches. After staying away from the spotlight for a few months while she healed, she released her single "Cry Pretty."

Underwood, who is 35 years old, recently came under fire for her comments in an interview with Redbook, where she talked about "missing" her chance to have several kids because of her age.

"I'm 25, so we may have missed our chance to have a big family. We always talk about adoption and doing it when our child or children are a little older."

Some fans were upset about her comments, and felt they were insensitive to those with struggling with fertility.
