Tim McGraw and Faith Hill

Although they're not colorful enough to warrant a Johnny 'n' June-like biopic, impossibly photogenic Tim McGraw and Faith Hill are without a doubt country music's reigning first couple, their 10-year union seemingly as strong as their combined album sales. The pair first linked up in '96, on McGraw's aptly named Spontaneous Combustion tour. He was already a bona fide star, thanks to his 1994 hit "Indian Outlaw," while Hill was an emerging Nashville favorite. By the end of that year, they were married, and two years later both were superstars -- Hill's breakthrough coming with her country-pop Faith album, which spawned the crossover smash, "This Kiss."

In 2000, they embarked on their hugely successful Soul2Soul co-headlining jaunt; in the six years since, McGraw has toured steadily, most recently behind his last (and best) album, 2004's Live Like You Were Dying, while Hill has stayed home raising their three young daughters (and putting out chart-topping albums). The couple returns to the road this summer -- with family in tow -- for Soul2Soul II: a nearly three-hour, intermission-free spectacle, during which the singers perform their own hits and occasionally team up for such googly-eyed duets as "Let's Make Love" and "Like We Never Loved at All."
