While fighting off divorce rumors, Faith Hill and husband Tim McGraw gushed about their on-stage chemistry for their Soul2Soul concert series at The Venetian in Las Vegas.

Since Friday, Oct. 25, the couple has hit the stage every weekend for the series.

Hill raved about her husband of 17 years and said, "he has this charisma and this unexplainable presence that exudes from the stage," according to The Associated Press. "It's magnetic and it's incredible. It comes from years of doing it, and he's definitely perfected his craft, but more than that, it's God-given."

McGraw, who said the concert series is a good chance for him to "catch his breath" after touring, also talked about his affection for his wife.

"She walks out, and just opens her mouth, and it just comes out so naturally...and soulfully," he said, according to Billboard. "That's what keeps me on my toes with her - first off, knowing she's out there singing and people have to listen to me behind that."

While they might have been performing in the 1,800 seat theater every weekend, Hill said she's more concerned about "what's for dinner" and being there for their oldest daughter Gracie, who's a junior in high school. She confessed that juggling both is hard to handle.

"I think this will probably be it," she said about performing with her husband. "It's increasingly more difficult with the high school thing. You've just got to be there."

The couple also told Entertainment Tonight having another kid is out of the question.

Hill said, "It is so busy with three girls. It's good..."

McGraw and Hill spoke about divorce rumors for the first time earlier in November. Hill told People, "I wish people would stop buying that stuff. Happy is good. I don't know why happy can't be a story."

The final Soul2Soul performance is set for April 12, 2014.
