The Masked Singer fans were blown away when the identity of Dragon was revealed in the semi-final.
For weeks viewers were convinced that the celeb hiding beneath the cute costume on the ITV singing show was RuPaul's Drag Race star Michelle Visage or Australian drag queen Courtney Act.
So it was a shock when Dragon turned out to be former Bake Off presenter Sue Perkins.
The former Celebrity Big Brother contestant had viewers watching at home fooled and none of the judges guessed that it was Sue.
Singer Louise Redknapp gasped on Twitter: "What a shocker!!!"
Emmerdale actress Lisa Riley exclaimed: "Wow wow wow.....no idea!!!"
TV presenter Gaby Roslin tweeted: "That was a shock and a half. You were sensational and wow wow wow what a voice."
"Ahhh Sue Perkins!!! Did not see that coming," said another viewer.
"Omg it's Sue Perkins!! This was the best surprise reveal," said another fan.
"Wow I absolutely LOVE @sueperkins and had no idea she could sing like that!" said another.
Sue, 51, tweeted after the reveal: "What an absolute RIDE.
"I loved every second of it.
"Thanks to all of MS team who helped me keep the secret - and most of all to Anna my voice coach and Steve the MD who helped drag the wee voice out of Dragon. Xxxxxx
(Ps. love to @michellevisage and @courtneyact)."
Sue said about her appearance on the secretive show, which has people guessing which celebs are hiding behind elaborate costumes: "I was strangely calm.
"I’ve always had a problem singing as myself – but everything felt better once I had a big mask on my head.
"I might try it in other stressful situations to be honest - like talking to traffic wardens or going to the dentist."
The Masked Singer, ITV, Saturdays at 7pm.
