Kacey Musgraves lit up the Grammys stage [1] in more ways than one on Sunday night. During the show, the country singer put her gorgeous vocals on display as she crooned her ballad "Rainbow" from her Grammy-nominated [2] album Golden Hour. As if her beautiful lyrics about holding onto hope even in the darkest times wasn't enough to make you tear up, we really lost it when the stage lights turned into an actual rainbow behind her. Don't mind us, we'll just be sobbing over this performance for the rest of the night.
