"My son. 💙 Another LIFE we get to love and cherish. Happy Mothers Day!" Barrett posted on her Instagram account. She did not say when she was due.

"Happy Mother's Day to my amazing, strong, and fruitful Bride! @gabbybarrett_She is currently carrying another precious life made in the image of God. A son to bear our name into the next generation. Our children will rise up and call her blessed, this husband also, praises her. Proverbs 31:28

"Praise God from whom all blessings flow!"

Barrett, who is slated to tour with Jason Aldean later this year, and Foehner are the parents of a one-year-old girl, Baylah May.

Barrett, 22, has released one album, "Goldmine" in EP and later deluxe form. She had hits with "I Hope" and "The Good Ones." The Pennsylvania native comes from a family of eight children.
