In Musgraves’s first interview since her Cinderella moment, the singer reflected on this year’s Grammys, her place in the Nashville scene and what’s to come. These are edited excerpts from the conversation.

Congratulations on a big night. How have you been celebrating?

Lots of R & R time. Definitely happy moments with the team, but also celebrating with food. Enjoying having some burgers — note the plural nature. My husband and I had some down time together — spa time, which is a way that I like to take a break. But I’m already back to a week of shows.

And how did you celebrate that night — did you go hard or just crash at the hotel?

I went really hard at Fatburger. I’m not like, hugely into an after-party scene, usually. I kind of like celebrating on my own terms. But we did stop by. And then afterward, not only did I have a fried chicken sandwich doused in buffalo sauce, but I also had a cheeseburger with jalapeños on it, and I ate both, 100 percent, and fries. I sat there and ate it in the restaurant in my Valentino dress. I went straight from shaking Mick Jagger’s hand to having a fried chicken sandwich in my hand.

What do you remember about the moment your name was called for that final award?

Disbelief, in general. But weirdly, a sense of calmness. Leading up to an award like that, you have a little hope, I think, that maybe you’ll win. But I was fine with not winning because it was just such a crazy compliment to be nominated alongside such giant albums. Huge albums that garnered lots of attention, lots of sales, lots of radio play. So you can hope that you may have a small chance, but I definitely was nowhere near banking on anything. It was a really beautiful moment, and I was somehow able to find the words to get out what I wanted to say. I don’t think it’s something that you can process until way later.

Who’s the funniest person who has contacted you to say congratulations? Any heroes, exes or elementary-school enemies?
