FAITH HILL MELTDOWN AS TIM MCGRAW PARTIES WITH BOOZING BUDDIES

The 10-year marriage of country superstars Faith Hill and Tim McGraw has hit a rough patch because of Tim's hard-partying ways, sources say.

And The ENQUIRER has learned that Faith's bizarre meltdown at the Country Music Awards in November was a result of the trouble brewing at home.

As Carrie Underwood's name was being announced as Female Vocalist of the Year, an ABC camera caught Faith initially raising her arms in triumph, apparently thinking she had won. But when the 39-year-old realized Underwood had nabbed the award, she turned to the camera and shouted, "WHAT?" and stormed off.

Her publicist claimed the next day that Faith was joking, but a friend told The ENQUIRER: "The meltdown everyone saw wasn't because Faith is a sore loser — it was because of her marriage troubles."

Tim and Faith are widely regarded as having one of the most stable marriages in country music, but friends say 39-year-old Tim "has been living something of a double existence in his personal life."

While he is a doting dad and adoring husband while he's home, he's also an "aging party boy" when he's hanging out with his longtime band mates and former college fraternity brothers.
