McGraw And Hill Never In Harmony When They Sing Together

Tim Mcgraw and fellow country star Faith Hill enjoys a harmonious marriage - until they sing together at home.

McGraw and Hill, who have three daughters together, often like to wind down by singing around the house, but it often leads to few flat notes.

McGraw says of his wife, "She always tells me not to sing harmony, because I can't sing harmony to save my a**.

"She'll go, 'You know better than that!'"

But despite the criticisms, McGraw admits he remains smitten with his wife of almost eight years.

He coos, "I'm one of her biggest fans."
