Perri was born and raised in Philadelphia. "Christina Perri has the voice of a oversized black woman in the body of a skinny, tattoo covered, hopeless romantic," according to her MySpace page.

Perri was featured in a Cricket Wireless commercial, according to her MySpace page.

Perri tells the story of "Jar of Hearts" on her blog.

She writes, "i wrote the song after i went home to philadelphia for the holiday last december. i sat in my childhood bedroom and hid from the boy (with the jar of hearts) who wanted to see me. my heart wanted to see him, my head knew better. i couldnt take one more break so i wrote the song instead."
