Lead vocals are performed by Holly Arnstein with speaking breaks by Melissa Schuman. Diana Ortiz can be heard saying a few Spanish phrases, such as Él me quiere ("He loves me") and No te quiere ("He doesn't love you"). An early version of the song opened with a young girl's voice saying "He loves me, he loves you not," though this opening was removed on the album and single versions, although the phrase "he loves you not" is heard at the end of the album version.
