Tim McGraw and Faith Hill recently celebrated their 19th wedding anniversary, and the couple are still madly in love and going strong after all these years.

The superstar says it's not difficult for them to maintain their relationship, despite so many high-profile breakups in country music of late.

"We just think about how much we love our family, how much we love our life together, growing old together, once your kids grow up," he tells E! "We feel pretty happy in the life that we've built together and the community we live in and the way we live our lives."

It won't be that long until he and his famous wife are empty nesters. Their oldest daughter, Gracie, is already off on her own.

"[Gracie's] a singer and a guitar player and writes songs and has a band, they played all this summer around town," McGraw says. "She's in school now. She's studying music. I want them to follow their passion -- all of them. And all of them can sing and all have different interests, but just to follow their passion. I'd like for her to get her college degree first, but whatever inspires them, whatever motivates them, whatever they wanna go for. That's what I'm all about."

Gracie's career got a nice shot in the arm when McGraw asked her to sing on a track from his upcoming album, Damn Country Music, which is set for release on Nov. 6.

"When we were working on this song, I just kept hearing her voice on 'Here Tonight,'" he says. "I was afraid to ask her because she’s way cooler than I am, and I was scared to death that she would say no."

They debuted the song live at McGraw's recent concert in Nashville. Take a look at that video below.

McGraw is also slated to headline at We Fest 2016, which takes place in Detroit Lakes, Minn. from Aug. 4-6, 2016. For more information on the hottest festivals of 2016, check out our handy 2016 festival guide.
