Pearl, Boogie Woogie, Mad Scientist and Coral, all nicknames for the costumes the celebrities don for their performances, duked it out in one final showdown − the winner nabbing the Golden Mask trophy and being forced to reveal themselves.

Boogie Woogie, Coral, Mad Scientist Monster, and Pearl take the stage for one last shot at the Golden Mask trophy in a nailbiter of a finale that left even the winner shocked -- so who won it all, and who are these four incredible singers?

In the final moments of the show, Pearl took off her mask and revealed herself as country singer Gretchen Wilson. Robin Thicke, one of the four celebrity judges on the show, was the only one of his colleagues to guess Pearl's identity.
