Sadly, the Mouse was made to leave after just her second performance for the show, singing This Will Be (An Everlasting Love) by Natalie Cole.
After a slight struggle with the mask, presenter Nick Cannon revealed that the legendary Dionne Warwick was in the Mouse’s costume.
Some fans were stunned, but many had already guessed that the six-time Grammy-winner and iconic R&B singer was behind the costume after recognising her voice.
Fans took to Twitter to voice their excited reactions, as well as pay tribute to Dionne’s illustrious career.
