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.
