Britain’s Got Talent judge Piers Morgan reportedly huffed like a child when Louis Walsh appeared on set with a badge declaring him ‘head judge.’

Louis was drafted in to replace Simon Cowell for this years Birmingham auditions, after Mr Cowell fell ill with the flu. Stephen Mulhern, who presents ITV2′s ‘Britain’s Got More Talent, told Now magazine: “Piers was in a mood and we couldn’t figure out why – it turned out it was because I’d given Louis a badge saying ‘head judge’. Piers was genuinely livid, but was soon all smiles when he got the badge.”

Stephen also revealed that despite being repulsed by Paul Hunn ‘The Burper’, Amanda Holden isn’t above a bit of flatulence herself!

He explained: “It was so funny that Amanda was so repulsed by the belching act Paul Hunn, because backstage she did a massive belch herself. Classic!”
