With two episodes left before the finale, four of theMasked Singersemifinalists 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 judgeJoel McHalepraised it as the “best performance I’ve ever seen on this show.”

Then Thingamajig and Tree went head-to-head. Flirting with judgeNicole Scherzingerin 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 judgesKen Jeong,Jenny McCarthy, Scherzinger,Robin ThickeandMcHalepicked Thingamajig to stick around for another week, sending Butterfly home.

HostNick Cannongave Butterfly a hand taking off her mask, and once they both managed to remove the bug head, Destiny’s Child memberMichelle Williamswas 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 inAida, Chicago and Once on This Islandon Broadway, said of her time onThe 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 comesthe year aftershe opened up about herbattle with depressionandbroke off her engagementto pastor Chad Johnson.
