Tim McGraw has shared some of his secrets to long-lasting marriage. During an interview at SiriusXM headquarters, the country star who is currently promoting his 13th studio album "Sundown Heaven Town", which is now available everywhere, talked about his relationship with Faith Hill whom he married 18 years ago.

"I think, for us, being as normal as possible and raising our family and being in a family situation as much as possible... Certainly it's different because of what we both do, but we try to keep it as much of a family environment that we can," he said, as quoted by E! News. "And most of the time...we try to make that the priority and the primary time that we spend. For us, we leave the front doors when we go to work, but when we're home, we don't talk about none of the music that much... It's a whole different world."

In a separate interview with Yahoo!, the 47-year-old singer gushed over his three daughters, saying that they all enjoy music. "Gracie, Maggie, Audrey, they all sing. Maggie, she'll sit at the piano at hours on end, trying to bang a song and learn a song. Gracie - she has a ukulele and a guitar and sits up there and plays. She doesn't like me to hear, though. I have to sort of lean outside her door to hear her sing but she's got a beautiful voice," the proud father said.

The singer also proudly talked about Audrey's performance at his recent show in Arkansas. "Audrey's probably the one who really takes singing the most serious and really wants to be a singer," he was quoted as saying.

"She had one time to run through it, she ran through it once, walked out on stage and just nailed it. And it was tough for me to sing after her because I was crying so much. I had tears running down my face," he continued. "I was just shocked that she just went through with it and did it, and did it so effortlessly! She definitely has got her mom's pitch and tone."
