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.

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.

Pearl shined during her performances on The Masked Singer season 13 and her powerhouse vocals moved the panelists and audience. Life & Style shares everything we know about Pearl, including fan clues and theories about the celebrity behind the costume before her identity was revealed during the finale.
