Louis Walsh has quite a past with the show's novelty acts, bring us the likes of Wagner and Jedward over the past few years. Speaking to the official ITV website today, Louis insisted that Johnny was different, it's just a shame we haven't seen it yet!
So far Johnny's performances have seen him camp it up to Cher's Believe, before going all Geisha on us with Kylie's Out Of My Head.
But Louis insisted: "Johnny is just like an old fashioned, music hall entertainer.
"Everyone remembers Johnny! He’s not a passing fad, he’s a phenomenal singer and the show would be dull without him.”
