Collings shocked the judges in the first audition show, winning high praise for his rendition of Tracy Chapman's 'Fast Car'. However, before he performed, judges Amanda Holden and Michael McIntyre mocked the Plymouth native for his baggy trousers and orange hoody.
Speaking on This Morning, Stephen Mulhern said: "When will we learn? When we looked at Michael, you look at him and we all made our judgements. We did it with SuBo, we did it with Paul Potts - this year surely we should have learned from our mistake.
"When he came on, even Amanda and Michael thought he looked like he was from easyJet. But if you closed your eyes and listened to him, he was just unbelievable. I hope he does well."
Britain's Got Talent continues on Saturday on ITV1.
