Popstar To Operastar's Joseph Washbourn has assured fans he will not break out into operatic spurts during his band Toploader's live shows.
The singer, who survived a sing-off against former Pussycat Doll Melody Thornton last night, is touring with his re-formed band this summer.
But he said he would be keeping his rock career well away from his classical efforts.
"I think we shall keep it strictly Toploader if it's a Toploader show. It would be a surprise for our fans for sure, but I doubt very much that I will burst into arias," he said.
Joseph found himself in the bottom two again of last week's show, following his previous showdown against soul diva Jocelyn Brown.
He said: "I feel like this TV show is like being in a boxing match at the moment."
"It is a TV show, so a lot of it runs on the phone votes and there are some strong fan bases out there."
Joseph has released a new Toploader single A Balance To All Things and album, Only Human, after teaming up with bandmates Dan Hipgrave, Matt Knight and Rob Green once again.
The 35-year-old musician reckons this weekend would be his "make or break" moment as he attempts to get his tongue around a composition in Italian.
"I'm not quite there with the language yet but it is a beautiful and stirring piece of music."
