The Grammy winner showed off a new, lighter hair look on Instagram Friday, sporting fresh blond highlights in place of her signature dark brunette ‘do.

“Lighten up, buttercup,” Musgraves, 31, captioned one of the selfies, adding a shout-out to her “mane man,” hairstylist Giovanni Delgado.

The “Rainbow” singer’s summer-friendly update comes only a few weeks after she and husband Ruston Kelly announced they were filing for divorce.

“It simply just didn’t work. Though we are parting ways in marriage, we will remain true friends for the rest of our lives,” the two country stars’ joint statement read.

“We’ve made this painful decision together — a healthy decision that comes after a very long period of trying the best we can. We hold no blame, anger, or contempt for each other and we ask for privacy and positive wishes for us both as we learn how to navigate through this.”
