The Masked Singer unveiled a big star in a very special episode
Demi Lovato was unmasked as a special one-time guest on the 10th season premiere of The Masked Singer

The whole gimmick of The Masked Singer is to reveal celebrity performers behind comically-themed costumes, but the usual level of celebrity isn’t exactly A-list. Competitors have included professional athletes, nostalgia acts, and singers who never fully “broke out.” Even the show itself has tacitly acknowledged that its stars aren’t particularly starry by inviting a one-time special celeb guest to kick off its 10th season: Demi Lovato.
Lovato is not one of The Masked Singer’s competitors—she just dropped by to perform Heart’s “What About Love” and promote her new album Revamped (which features rock covers of previous hits). But they still played the game, dressing up as “Anonymouse” and providing the judges with clues. “Just like Michelle Obama, Oprah and Angelina Jolie, I’m on one special list: Time’s 100,” was one of the hints (via Variety). The second clue was a concrete slab that said “Anonymouse,” with the explanation “This is a literal concrete clue. My acting career has cemented me as one talented mouse.” (They’re a Disney kid—get it?)
