Country queen Faith Hill is urging her husband Tim Mcgraw to read self-help parenting books because she fears he'll become a tyrant when their daughters start dating.

He means good but you don't want him going so far it's unrealistic. "I can see him saying, 'He's sitting too close to her. Go do something about it."
