Tim McGraw Sings a Duet With His Daughter Gracie

The singer has three daughters with wife Faith Hill.

The 18-year-old recently joined her famous dad on stage for his Nashville, Tennessee, concert.

The eldest daughter of McGraw and Hill took the stage Saturday evening to sing part of her dad's new song, "Here Tonight," before thousands of screaming fans.

"I mean, I have sledgehammer. I want it to be visceral," he said. "No, I'm not that tough. I mean, I try to act like I am, but I just want them to be happy. I want them to have a good time."
