The girl group argued that previous winners had used emotional stories from their lives to help them beat technically superior singers.
"I think it's nice that we don't have a sob story because every year there is one," said Stacey Lincoln.
"Sometimes you feel like people don't win on pure talent. We're just totally normal girls that want to win a talent competition."
Emily McNamee said: "It doesn't annoy us, but I think even some people in the house who have had emotional events in their lives are getting a bit upset by it all. They want people to recognise them as a singer as well."
Sophie Wilson added: "I think a story can get you through to a certain point, but after that it is down to pure talent."
