1. Thomas Rhett celebrated his wife of eight years.
These two are going strong! Everyone knows the story of Thomas and Lauren: The two are childhood sweethearts, growing up in grade school and church camp together, dating briefly in high school and then finally going the distance and getting married when they were both just 22 (which Rhett details a little bit in his song "Life Changes"). Things are going well, though, as the two are celebrating eight years with three little girls -- Willa, Ada and Lennon -- along for the ride.
