It’s been a big year for the couple as Underwood, 36, welcomed their second son, Jacob, in January 2019 after revealing in late 2018 that she had suffered several miscarriages.

“I kind of planned that 2017 was, you know, going to be the year that I work on new music, and I have a baby,” Underwood said in a candid interview with CBS Sunday Morning’s Tracy Smith in September 2018. “We got pregnant early 2017, and it didn’t work out.”

"Got pregnant again, early 2018. Didn't work out. So, at that point, it was just kind of like, 'Okay, like, what's the deal? What is all of this?'”

The country star explained that each miscarriage led her directly to writing more music.

"'Cause I would literally have these horrible things going on in my life, and then have to go smile and, like, do some interviews or, like, do a photo shoot or something, you know? So it was just kind of, like, therapeutic, I guess,” she explained at the time.
