Boone is getting a brother.

Eric Church and wife Katherine are expecting their second child, another boy, his rep confirms to PEOPLE.

The musician, 37, slyly made the announcement on stage Thursday, tweaking a lyric in “Sinners Like Me” from “Give my dad a grandson of his own” to “Give my dad another grandson of his own,” CMT reports.

The couple was married in January 2008 in North Carolina and welcomed their son Boone McCoy, who turns 3 this coming Friday, in 2011.

“Everyone always tells you what an awesome and unique experience being a parent is, but words can never do the feeling justice,” Church said at the time.

“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.”

Church is on the road through December in support of his latest album, The Outsiders.
