'The Masked Singer': Fox Hints at Surprising Connection to the Judges (VIDEO)

The Masked Singer resumes its second season after a brief holiday hiatus on Wednesday, December 4, with a brand new episode featuring the four remaining contestants.

The competition is heating up as the season nears its December 11 finale, and in an exclusive sneak peek for this week's episode, we see Fox drop a major clue to the usual panelists and guest judge Joel McHale.

The disguised celebrity has stumped Nicole Scherzinger, Jenny McCarthy, Ken Jeong and Robin Thicke since the beginning. The celebrity guessed the most for Fox's identity is actor, singer, and comedian Jamie Foxx. Meanwhile, others tossed around have included Backstreet Boys' AJ McLean, Boyz II Men's Shawn Stockman, and This Is Us star Sterling K. Brown.
