Of her famous track, she shared: "When it first came out, it was more of a gradual thing. It was popular, but it didn’t have what it has now. I feel like people have grown up with the song and it’s become a part of people’s lives in terms of the way they celebrate the holidays. That makes me feel really proud as someone that loves Christmas so much."
