Tim McGraw and Faith Hill's daughter Audrey McGraw has followed in her parents' footsteps as a singing sensation, and she'll never stop championing their own achievements. "Coming from a Mississippi woman and a Louisiana man, who just got inducted into the Country Hall of Fame," Audrey, 24, said of her parents during a recent concert in Las Vegas. "My God, I'm just so, so proud of my dad [and] of both of my parents. I love them so much." Tim and Hill, both 58, have been married since 1996, during which time they welcomed Audrey and her sisters Gracie, 28, and Maggie, 27.
