Tim McGraw still has some time before his three daughters begin dating, but he's already planning his strategy for their protection, especially for his oldest, 11-year-old Gracie.

In a recent interview with Family Circle magazine, McGraw says, "I've jokingly told my friends who have sons the same age as Gracie that I'm going to hit the nicest boy of the bunch right off the bat, So when he goes to school with a black eye, all of the other boys will see that I've punched the nicest one, and they'll be scared to death of me."

Tim admits he's might be "in denial" that his daughters are growing up, but he's well aware of where he stands in his estrogen-filled household.

"My girls have me wrapped around their little fingers," says McGraw. "We also play dress up, and I let them put make up on me. But even if we're grocery shopping, it's still a good time."

Maggie and Audrey, Tim's younger daughters with Faith Hill, are 10 and 7, respectively.
