“The Masked Singer” goes to great lengths to make sure that contestants do not get revealed before their eliminations. So much so, that even the travel from the car to the studio is planned well in advance — and there are clothing guidelines.“You’re completely covered. You’re wearing a hoodie, you have this mask on, you’re wearing gloves, can’t wear shorts,” Tyler Posey, who was revealed as Hawk on Wednesday night’s episode told The Post.
