Brooks' daughter, August, gave birth to a baby girl named Karalynn. The singer released a statement thanking everyone "for their warm wishes and sweet celebration of Baby K's arrival."
Brooks also announced that he plans to continue living in semi-retirement in Oklahoma, but is considering returning to music full-time when his youngest daughter, Allie, graduates high school next year.
"Our children's lives have always been extremely private and they have been endlessly encouraged to be their own people," Brooks said "We have always wanted them to be individuals and not be known as 'someone's daughters.'
"I have been amazed and grateful how the press has always respected this. I now ask that respect to please continue as this young family begins the greatest days of their lives."
