"The memories we have created every time we have gone out have been the best memories of our career," McGraw said. "And we have two kids in college, what else are we gonna do?"
Soul2Soul kicks off April 2017 in New Orleans and will hit 65 cities around the world. The tour comes on the 10th anniversary of the duo's record-breaking Soul2Soul II tour, which was the highest-grossing multi-year country music tour of all time.
Hill and McGraw tied the knot on Oct. 6, 1996, after meeting and falling in love on McGraw's Spontaneous Combustion tour. McGraw recalled the story in his acceptance speech on Wednesday, calling it "the best thing that happened to me."
"I had a really hot chick on the road with me," he joked. "And I fought, and I fought, and I fought to stay away from her as long as I could, and that lasted about as long as her job at McDonalds. I'm not gonna go into detail, but it was a great tour. I can tell you that."
Since then, McGraw and Hill have raised three daughters: Gracie, 19; Maggie, 18; and Audrey, 14.
Gracie McGraw already seems to be following in her parents' musical footsteps, even appearing on a track from her dad's latest album, Damn Country Music.
"She's way more talented than I am," McGraw gushed at the ACM Awards earlier this year. “She's so bubbly and she fills up a room when she walks in. She's got so much talent and is such a great songwriter, we're going to hear from her down the road, for sure."
