This mystical love song finds Perry describing the eternal passion between herself and her beau as well as namechecking legendary lovers Egyptian Queen Cleopatra and Shakespeare's tragic heroine, Juliet. She sings on the chorus:
"Take me down to the river
Underneath the blood-orange sun
Say my name like a scripture
Keep my heart beating like a drum."
Perry penned the song in her hometown of Santa Barbara with her frequent collaborators, Bonnie McKee
, Henry Walter, Max Martin and Dr. Luke.
