‘The Masked Singer’ Includes First Two-Headed Costume Duet

“The Masked Singer” will introduce its first-ever two-headed costume this fall, the “Snow Owls.”

When Season 4 launches on Sept. 23 at 8 p.m. ET, the “Snow Owls” will be joined by previously revealed costumes including the “Crocodile,” the “Sun,” the “Giraffe” and the mysterious “Whatchamacalit”, among other costumes.

The “Snow Owls” represent the first duet celebrity contestants in the show’s history. Will they sing “I’ve Got You Babe,” by Sonny & Cher? “It Takes Two,” by Marvin Gaye and Kim Weston? Will they not be internationally known but known to rock a microphone like “It Takes Two’s” Rob Base and DJ E-Z Rock? Is it the Olsen Twins, stars of the classic 1995 film “It Takes Two”? All great questions.

Before “The Masked Singer” returns on Sept. 23, Fox will also air a special Season 4 sneak preview on Sunday, Sept. 13 at 8 p.m., where more info will also be hinted at.
