YouTube sensation and former 'Dance Moms' star is revealed on 'The Masked Singer'

The T-Rex may be a dyn-o-mite dinosaur, but when her identity was revealed on Wednesday’s pre-semifinals Masked Singer showdown, the rockin’ reptile ironically turned out to be the youngest contestant in the series’ history. Yes, beneath all those scabby scales lurked 16-year-old YouTube sensation and former Dance Moms child star JoJo Siwa. While JoJo’s fans, the Siwanatorz, were probably outraged over the T-Rex’s early extinction, the perky pop phenom maintained her usual happy attitude upon receiving the news — even taking the opportunity to reprise her Wednesday performance, the Pussycat Dolls’ “Jai Ho! (You Are My Destiny”), with the woman who originally sang and co-wrote the Slumdog Millionaire hit, judge Nicole Scherzinger.
