"We are very excited," Barrett told PEOPLE magazine. "The Lord has blessed us with a little one, and we're really excited to finally be able to share the news with everybody and just have a big old family celebration about it."
Barrett, 20, and Foehner, 24, married in October 2019. Their baby girl, the couple's first child, is due early next year. Barrett told PEOPLE she found out she was pregnant in May.
"We were in Texas visiting Cade's side of his family," Barrett said. "And it's funny, because I did not think that I was. Around lunchtime, I remember taking the test and my eyes nearly crossed! I was like, 'Wait, is that two lines?' I came running out to Cade and was just like, 'Oh my gosh, I think I am.' That's all that I said, and he knew what that meant. I started crying, and it was very sweet."
Barrett finished in third place on season 16 of American Idol. She released her debut album Goldmine in June. Foehner was eliminated during Top 5. He's now performing as a solo artist.
Barrett hit No. 1 earlier this year with her song "I Hope." Along with rising country artist Ingrid Andress, Barrett made Billboard chart history as the first time in the chart's 30 year history that two women's debut singles simultaneously made the top 10.
