Who was the first winner of 'The Masked Singer' (US)?

The first winner of the U.S. version of The Masked Singer was T-Pain. He won the show's first season in 2019 while performing in the elaborate Monster costume, keeping his identity hidden until the finale.

The American series premiered on Fox on January 2, 2019, and concluded on February 27. Its format combined celebrity singing performances with clues, guesses from a panel, audience voting, and elaborate disguises designed to conceal each performer's identity. Twelve contestants competed in the first season.

T-Pain's victory was followed by Donny Osmond as the Peacock, while Gladys Knight finished third as the Bee. The result is sometimes confused because all three finalists were famous singers, and the show's clues encouraged speculation about multiple identities. T-Pain was already known for his use of Auto-Tune and hits such as “Buy U a Drank,” but the costume and altered presentation made him less immediately recognizable to viewers.
