It's the second son for the 'American Idol' runner-up

The youngest member of the Bice Squad has arrived.

"American Idol" season 4 runner-up Bo Bice and his wife Caroline Fisher welcomed a baby boy on Tuesday, Aug. 5, reports Usmagazine.com.

Baby Caleb is the couple's second son. The couple, who wed in July 2005 in Helena, Alabama, are also the parents to Aidan, who will be 3 in September.

"[Caleb] is a good biblical name," Bice said at the "American Idol" finale show in May. "We stuck with that with both kids -– good Irish and good biblical names."

Last year, the 32-year-old rocker opened the record label Sugar Money and released his album "See the Light."
