Tim McGraw isn't shy about showing off his lady, even 20 years into marriage. While in the car this week, the singer snapped a shot of only wife Faith Hill's legs and posted the photo to Instagram.

Her long stilts peek out of a black and white dress draped over the top of her thighs as she peers at her phone. The caption sweetly reads, “Bam … my bride!” showing McGraw's genuine pride in his beautiful wife.

McGraw and Hill will celebrate two decades of wedded bliss on Oct. 6 — a feat for anyone, but particularly for a celebrity couple. The two have raised three daughters together and still kept individual careers thriving throughout the years. Their 20 years together has taught them a lot, McGraw says, including his number one rule: Listen. The artists jokes that he really has no choice, though, living with four women.

"And I’ve also learned," he adds, "that when you look at politics and you look at the world we live in and everything else, there’s really no definite answers to anything. There’s a lot of sort of figuring your way out with every move that you make. I think that you find that out as you get older and that really has to do with relationships, as well."

McGraw jokes that his input doesn’t really have much pull in his family anyway, saying, "I don’t really have a lot of say-so at my house."

The country couple's eldest daughter, Gracie, is now off at college, and McGraw says his recently-released song “Humble and Kind” hit home in light of her transition into adulthood. Their second daughter, Maggie, is just beginning college, and their youngest, Audrey, is beginning high school. The proud dad couldn't be more proud of the young women they have become.

McGraw played WE Fest this summer as a headliner and just released a new single called “How I’ll Always Be” from his latest record Damn Country Music.
