Demi Lovato unmasked after fiery performance on ‘The Masked Singer’

The 10th season of "The Masked Singer" started off with a special episode on Sunday and fans were treated to "one of the biggest" unmaskings in the show’s history.  

The first celebrity guest reveal of the newest season turned out to be none other than Grammy-nominated artist, Demi Lovato. 

"I wanted to do your show because it seemed so fun and it has been so fun and I get to sing," Lovato said after removing her mask. "It’s the best of both worlds."

Kicking off the newest season of "The Masked Singer" with "What About Love" by Heart, Lovato’s powerful voice and naturally charismatic stage presence left judges speechless. 

Her fiery performance also left judges with no question as to who was behind the mask as "there’s only a couple of people" who have such a dynamic singing voice, according to panelist Jenny McCarthy Wahlberg. "Demi Lovato being one of those legends," Wahlberg added.
