Eric Church is going to be a dad of two!

The 37-year-old country music singer and his wife Katherine Church are expecting their second child together, a rep for the performer confirmed to E! News.

The "Give Me Back My Hometown" hitmaker hinted at the baby news during his concert in Louisville, Kentucky last week, which is part of his ongoing "Outsiders World Tour," according to CMT.com.

Church was performing his 2006 single "Sinners Like Me" Thursday, Sept. 25, when he altered the lyrics to the song to subtly announce the pregnancy of his wife.

While the original lyrics read, "Well now maybe who knows one day I'll settle down / Give my dad a grandson of his own," Chruch shouted out, "Give my dad another grandson!"

The couple is already proud parents to son named Boone McCoy, who is turning 3 years old this coming Friday, Oct. 3.

"Everyone always tells you what an awesome and unique experience being a parent is, but words can never do the feeling justice," Church told People in December 2011.

"The way our life changed in that 24-hour period alone after he was born - just by putting a little boy in the house - was awesome," he added. "I've always made music that was representative of real life. Life doesn't get more real than having a newborn at home."

Just this June, the "Cold One" crooner opened up to Billboard about being a father.

"When you have a child, everything changes," Church said. "I've changed a lot. I suppress a lot of maybe the way I used to be. Is that dark side still probably there? Yeah. I just don't let it come out very much. But if you mess with my kid, if you mess with my family, well, I can bring it out."

The North American leg of Church's "Outsiders World Tour" is expected to close towards the beginning of December, E! News reported.
