The show, hosted by Nick Cannon, follows 12 celebrities from different lines of the entertainment industry, as they come up with their own extravagant costume to sing for judges Robin Thicke, Ken Jeong, Jenny McCarthy and Nicole Scherzinger. The judges then have to guess who's behind each mask.

In the premiere, six celebrities took the stage, and the "Hippo" was revealed to be football player Antonio Brown. Five more characters remain: The Monster, the Peacock, the Deer, the Lion and the Unicorn. Fans have stormed Twitter to try to guess who's behind the remaining masks.
