"The Masked Singer [1]" is officially back for its 10th season. After a special episode featuring Demi Lovato [2] aired on Sunday, Sept. 10, the hit singing competition show returned on Wednesday, Sept. 27, with longtime judges Robin Thicke, Jenny McCarthy [3] Wahlberg, Ken Jeong, and Nicole Scherzinger and host Nick Cannon.

Considering this is the show's 10th season since it premiered in January 2019, it's set to be the biggest one yet. "After nine incredible seasons, if I had to put money on it, this is the best season ever," McCarthy Wahlberg said in a Sept. 18 promo video [4]. Besides new themes, the upcoming episodes of "The Masked Singer" promise to have more elaborate costumes, as well as bigger celebrity reveals. Following the season premiere, the panelists have guessed that anyone from Adam Levine and Usher [5] to Scott Disick and Vanessa Hudgens [6] could be a contestant this time around.
