“Cause I know my place, and it ain’t with you/ Sunsets fade, and love does too / Oh, we had our day in the sun / When a horse wants to run, ain’t no sense in closing the gate / You can have your space,” Kacey Musgraves sings on her award-winning album, Golden Hour. Coincidentally, it appears everything’s golden between Kacey, 31, and husband Ruston Kelly, 31.
