It was a double elimination on The Masked Singer last night. I'm not putting anything behind a spoiler cut, though, because we all know that no one actually cares about this stupid show. Anyways:
The Caterpillar was revealed to be: Bobby Berk, the designer from Queer Eye
The Mallard was revealed to be: Willie Robertson, the guy from Duck Dynasty
So. There you go. I think the finals might be next week?
