X Factor hopeful Johnny Robinson has revealed he longs to team up with singing legend Dame Shirley Bassey.
After covering the Welsh diva's songs as part of his drag act for years, the 45-year-old singer said he would love to duet with her in person. Robinson also spoke of his delight after learning that Kylie Minogue was impressed by his performance of her hit, Can't Get You Out Of My Head.
"That was a real compliment, coming from such a well-known, established, hard-working female artist. A pop princess, I should say! I was well smitten," he revealed. "I love a bit of Kylie."
Robinson - who is expected to perform a track by The Darkness on Saturday night's show - said he would love to perform alongside a music legend as a result of appearing on the ITV1 show.
"My dream collaboration would be Shirley Bassey, because she's amazing. Someone who's got longevity and are artists, they are proper icons," he said.
Robinson continued: "People that I aspire to like Tina Turner, Barbra Streisand, Kate Bush, George Michael - I think he's a great singer, I'd duet with Elton John.
"All the greats - David Bowie, people like that - the people who have been in the business for a long time and are not just a product for two years and gone. They are people who actually work hard for their craft."
Robinson, who is being mentored by Louis Walsh, admitted he is "a bit worried" about Saturday's performance. He said he does not feel comfortable belting out a rock track.
"I was a bit worried because it's 'rock week' and obviously, I haven't really done any rock numbers before. I thought I was doing a ballad, but it's not," he said.
But he plans to take it all in his stride, no matter what happens: "I'm looking forward to it, it's good fun and it's a challenge, and that's what it is all about, isn't it?" His novelty performances have won over the public and the judges, as he escaped being in the bottom two last week.
