Faith Hill would prefer it if you left her husband's nether regions alone!
At her Soul2Soul tour stop in Lafayette, LA on Saturday night, one fan got a little grabby with Faith's better half, Tim McGraw -- and Faith ain't havin' none o' that!
"Somebody needs to teach you some class, my friend," Faith scolded the fan. "You don't go grabbin' somebody else's -- somebody's husband's balls, you understand me? That's very disrespectful."
Stand by your man's ... balls.
