"I've always loved Christmas so much my entire life, but I grew up not having a lot of money and not being able to experience it like the other kids did," she said.
"I wanted Christmas to be perfect, but for a lot of different reasons, it didn't always end up working out well, coming from such a dysfunctional family," she added. "So I think when I wrote it, I just put every ounce of longing for that perfect moment in it."
