The clues: The clue video for the Popcorn featured a handful of references to NYC as well as Sex and the City. Maybe someone who made a cameo. There was also a shot of meatloaf, a gold fisher wearing big hoop earrings, and a Proud Merry-Go-Round.
Who it could be: Based on the "Proud Mary" reference, the judges guessed Tina Turner. However, like Nicole Scherzinger pointed out, the goldfish wearing hoops could be a reference to Mary J. Blige who often sports big earrings.
