Bo Bice and his wife Caroline Fisher welcomed their second son on Tuesday, his rep confirms to PEOPLE.
The baby boy, named Caleb, was born in Nashville. He joins big brother Aidan
, who will be 3 in September.
"[Caleb] is a good biblical name," Bice, 32, said in May
. "We stuck with that with both kids – good Irish and good biblical names. We're just blessed to have such a beautiful family."
Bice, who released his latest album See the Light
on his own Sugar Money label last October, resumes his summer tour
later this month.
