It's not a whodunit - it's a "who-sung-it"!
In The Masked Singer, celebrities face off with one another but with a major twist: they're covered from head-to-toe in a costume, and it's anyone's game to figure out who they are.
It premiered on Wednesday, January 2nd at 9 p.m. on FOX, and the first singer - dressed as a stylized hippo - was revealed.
According to FOX's website, performers include Grammy Award winners to legendary athletes, and everything in between.
The show is hosted by Nick Cannon, and features panelists Jenny McCarthy, Nicole Scherzinger, Ken Jeong and Robin Thicke.
