When it came time for the studio audience and judges to vote on their favorite performance of the evening, they shockingly left Mouse, who sang what seemed to be a professional-level rendition of Natalie Cole’s “This Will Be (Everlasting Love),” in last place. All of the panelists, with the exception of Jeong, suggested that five-time Grammy winnerDionne Warwickwould be under the Mouse costume — and they guessed right!

“I’m just freaking out. I love you so much,” Scherzinger said.

Warwick, 79, appreciated the compliment and said she had “a ball” on the Fox singing competition.

“It has been an absolute pleasure,” the “That’s What Friends Are For” crooner said after being unmasked. “I had the best time.”

Dionne Warwick

Before Warwick revealed her identity, McCarthy thought there was “no way” the storied musician would be on the same season as 10-time Grammy winner and “Every Woman” singer Chaka Khan, who wasunmasked as Miss Monster two weeks earlier.

“There’s no way the producers would have Chaka Khan — a legend — and then Dionne Warwick on the same season,” McCarthy said.

Jeong quipped, “We’re out of legend budget!”
