Michael Schneider Variety Editor at Large SPOILER ALERT: Do not read ahead if you have not watched Season 11, Episode 10 of “The Masked Singer,” “Quarter Finals: Final Four,” which aired May 8 on Fox. “This Is Us” star Chrissy Metz knew “The Masked Singer” would be a challenge. But that’s why Metz, who was revealed as latest celebrity to be unmasked on Wednesday night’s quarter finals, figured she had to do it. “When I watched the show, and I would see either my friends or peers on the show, I’m like, how do they do it?” said Metz, who was revealed as the Poodle Moth.
