'In Another's Eyes' - Garth Brooks and Trisha Yearwood (1997)

Lines We Love: "In another's eyes/ I'm afraid that I can't see/ This picture perfect portrait that they paint of me"

They'd harmonized on each others records for years, but their first proper duet was also a sign of things to come -- Garth and Trisha began dating in 2000 and were married in 2005. In anyone's eyes, that's quite a love story.
