Russell Watson has denied claims he is Traffic Cone on The Masked Singer UK but says he is "absolutely certain" he knows who is.
The opera singer was quizzed over the speculation during an interview on Good Morning Britain with Susanna Reid and Adil Ray.
"I know who that is," Russell told the presenters. "The strange thing is, I didn't know who it was when I saw the first performance, I had no idea.

"Then I heard the second performance and I know who it is."
"I'm absolutely certain," he added.
Sharing who he thinks is behind the mask, Russell revealed: "He's not admitted it, he's not mentioned it at all, but I'm convinced that is my mate Aled Jones."
And he's not alone, many viewers at home also think the Welsh singer could be behind the mask.
Russell could of course be bluffing, with both broadcasters left unsure over his response.
It comes after Rob Beckett "accidentally" revealed he was behind the Traffic Cone costume during Saturday's show.
He wrote on Twitter: "'Just send this out once I've been unmasked'
"Thanks for all the support being the Traffic Cone I absolutely loved it. Great show.
"The kids couldn't believe it was me."
The Twitter post, unless an epic double-bluff, was widely thought to be a joke by the comedian.
Other guesses for Traffic Cone have included Sir Tom Jones and The Chase presenter Bradley Walsh.
