Carol Vorderman, 61, has given life to speculation that she is Mushroom on ITV’s The Masked Singer following the character’s impressive performance on Saturday night’s show.
The mystery star has given clues like taking the panel “back to school”, “soaking up and communicating knowledge” and references to presenting.
Following Mushroom’s performance to Crazy by Gnarls Barkley, Davina McCall suggested it could be the Countdown star behind the mask.
The judge said: “Previously we have talked about her fantastic brain. There has been mention of numbers and educating people.
“And, she is crazy, I know that.

“I am thinking of Carol Vorderman, but I have never heard Carol sing.”
However, fellow judge Jonathan Ross attempted to quash rumours by chiming: “I have heard her sing once, I haven’t fully recovered.”
After the show aired, Carol retweeted a post from The Masked Singer’s official Twitter account which listed the presenter as an official guess.
Several fans also think Carol is behind the earthy costume.
Carol, who is best remembered for co-hosting Countdown for 26-years, is not known for her voice but has done some singing throughout her career.
In the early 1980s she was a backing singer for pop group Dawn Chorus and the Blue Tits.
Other members were radio presenter Liz Kershaw and Lindsay Forrest.
Their most notable hit is a cover of The Undertones’ Teenage Kicks.
Carol also showed off her voice as Cher on a celebrity version of Stars In Their Eyes in 1998.
She was decked out in a black curly wig, leather jacket and fishnet tights and belted out the lyrics to The Shoop Shoop song.
However, Carol has since confessed she found the whole experience “traumatising”.
Speaking on her BBC Wales radio show earlier this month, Carol explained: “We went in and you all do the introductions first, so you go: ‘Tonight Matthew, I’m going to be Cher…’ the audience went mental.
“I came out as a tart dressed in leather!
“[I came] through the smoke and there is no intro on this track, no music so you can walk down to the mic.
“You have to just start, and the audience seemed so loud I couldn’t hear anything…everything went so wrong.
“I started crying! I was in such a state of trauma… I died when I watched it, it was just so traumatic.”
The Masked Singer continues Saturday at 7pm on ITV.
