Hit song covers! Panelist Ken Jeong’s horribly bad guesses! Shocking masked celeb reveals! The Masked Singer has delivered its share of shocks over the years.

The outlandish hidden-celebrity competition nears its return on Sunday, September 10, on Fox (it then takes a two-week break before returning to its regularly scheduled air day on Wednesday, September 27, at 8/7c). And Fox promises “one of the biggest, can’t-miss unmaskings in the show’s history” in the first episode. Could it be one of the new characters, Donut, Anteater, Hawk, Hibiscus, or S’More?

The premiere will include guest appearances from past cast members such as Michelle Williams and Rumer WillisJoey Fatone and Bow Wow, and Victor Oladipo and Barry Zito, who will perform new duets unmasked. Expect a new format this season, in which the 16 contestants will face off in three groups before competing in a Battle Royale semi-final for each grouping. The Wild Card and Ding Dong Keep It On powers will also be part of the new episodes.
