Listen to Garth Brooks on iHeartRadio

There's a new lady in Garth Brooks' life.  The country superstar is now a grandpa with the birth last week of Karalynn, the first child for Garth's 19-year-old daughter, August. 

Brooks tells "Tulsa World" that his family appreciates the "warm wishes and sweet celebration of Baby K's arrival."  But he adds that he hopes the media will respect his daughter's privacy as she begins this new chapter of her life as a mom. 

August is Brooks' middle child.  The singer, who's currently married to country star Trisha Yearwood, has three daughters with his ex-wife, Sandy Mahl.
