After becoming a breakout hit last season, Fox’s hidden-celebrity singing competition, “The Masked Singer,” is back with Season 2 on Wednesday night!

With all-new episodes comes all-new costumes and contestants. Fans will once again get clues during each Nick Cannon-hosted episode that’ll help them guess the celebrities under each mask, with the returning judges/commentators — Ken Jeong, Jenny McCarthy, Nicole Scherzinger and Robin Thicke — sharing their best theories along the way, as well.

Before the premiere airs tomorrow, though, there are already some clues out there for fans to dive into as the network aired a special sneak peek episode of “The Masked Singer” Season 2 a couple of weeks ago, featuring video clue packages and some performance clips.

Below, check out all 16 of the costumes for Season 2 of “The Masked Singer,” as well as the clues shared during the pre-premiere sneak peek and a couple of our contestant guesses.
