"He and Faith have been fighting a lot recently — and he's tired of it all. He was making a big statement by performing without his ring at such a huge festival," a friend allegedly told the mag.

"Faith has been trying to make things work. She wanted to do something special for their anniversary, but he said no," the insider added.

A rep for McGraw tells Gossip Cop the tabloid’s story is "not true," noting, "Tim and Faith are very happily married and these accusations are ridiculous."
