The judges all figured out pretty quickly that the Hippo was not a professional singer. After his performance of “My Prerogative” by Bobby Brown, they guessed it was likely an athlete behind the mask, with guesses including Odell Beckham Jr. of the New York Giants.
However, it was Antonio Brown, who was very recently released from the Pittsburgh Steelers after a dispute with QG Ben Roethlisberger. We don’t think it had anything to do with his singing ambitions, though.
His clues included his experience performing in a mask in front of thousands of “screaming fans,” and being known for dancing every time he wins (even if it gets him in trouble) — and Antonio definitely knows how to celebrate in the end zone.
