The Masked Singer's Butterfly Revealed as Destiny's Child Singer Michelle Williams

Dana Rose Falcone

With two episodes left before the finale, four of the Masked Singer semifinalists sang for a chance at the Golden Mask on Wednesday night.

Butterfly and Fox paired off for the first showdown, and following both performances, the studio audience decided Fox’s take on “Haven’t Met You Yet” earned him the right to move on in the competition. Guest judge Joel McHale praised it as the “best performance I’ve ever seen on this show.”

Then Thingamajig and Tree went head-to-head. Flirting with judge Nicole Scherzinger in his clue package and again on stage couldn’t keep Thingamajig safe, though. Tree jingled her way to the next round with a rendition of “Total Eclipse of the Heart,” leaving Butterfly and Thingamajig to battle it out in the showdown round.

Ultimately judges Ken JeongJenny McCarthy, Scherzinger, Robin Thicke and McHale picked Thingamajig to stick around for another week, sending Butterfly home.

Host Nick Cannon gave Butterfly a hand taking off her mask, and once they both managed to remove the bug head, Destiny’s Child member Michelle Williams was exposed. “I knew it!” Cannon gasped after Williams’ unmasking. McCarthy, Scherzinger and Thicke had guessed Williams, 40, as well.

“It was a beautiful experience,” the former girl group member, who appeared in Aida, Chicago and Once on This Island on Broadway, said of her time on The Masked Singer. “Yes I’ve been on big stages, but for me personally, this was something for me to know like, ‘No, you got this!’ What a confidence builder. And you’re right, you know, I haven’t worked all year, since December of last year, so this was a way to come back strong.”

Williams’ participation in the Fox singing competition comes the year after she opened up about her battle with depression and broke off her engagement to pastor Chad Johnson.

Read on for the clues that helped the judges suspect Williams was under the Butterfly disguise, plus the additional clue each contestant gave following their performance.
