Watch Country Stars Unmasked In Jaw-Dropping Reveals On 'The Masked Singer'

Did you guess the country stars who competed as a Pearl and a Mad Scientist on The Masked Singer?

Celebrities compete against one another in the “top-secret singing competition” show wearing elaborate disguises to hide their true identities when they take the stage. Nick Cannon hosts the show, which features panelists Ken Jeong, Jenny McCarthy, Rita Ora and Robin Thicke, guessing whose voice is behind each stunning costume. The finale of the 13th season aired on Wednesday night (May 7), unveiling the celebrities who became known throughout the competition as Pearl, Boogie Woogie, Coral and Mad Scientist.

Unmasking reveals showed that Boogie Woogie was singer-songwriter and producer Andy Grammer, and Coral was Zombies star Meg Donnelly.

Country star Brian Kelley took the stage disguised as a Mad Scientist on The Masked Singer. Kelley said his “journey as the Mad Scientist Monster was UNREAL,” as he posted photos on Instagram to remember the “amazing experience” on the show. McCarthy didn’t mask her excitement after she correctly guessed the Mad Scientist’s true identity.

“Man, I just thought it was a different opportunity to, you know, kind of get out there, get my voice out there to the world, challenge myself (and) do some songs that I might not typically, normally do,” Kelley said when Cannon asked about his decision to compete on the show. “And I’m a little kid at heart, so putting on this whole mask and this whole suit was, it was a good time.”

Pearl won the show after her performance of “Black Horse and the Cherry Tree” by KT Tunstall. Watch the performance here, and watch the reveal below.

Pearl was revealed as Grammy winner and “Redneck Woman” icon Gretchen Wilson.

Thicke correctly guessed Wilson’s identity before she was unmasked. The “Here for the Party” superstar said she “had a rough couple of years,” sharing that she was injured and in a wheelchair, “and there was a moment where I didn’t think I’d ever get back to this place. And I worked really hard. I prayed really hard. And I got so far, but this opportunity has really proven to me that there’s nothing I can’t do.”
