Singer Charlotte Church has become embroiled in a row with X Factor bosses after they branded her ‘boring’.

The Welsh singer had previously revealed on Twitter that she had turned down the chance to join the panel of the series, saying she would rather ‘poke her eyes out with sticks than be a part of the machine that kills music’.

However a source told the Sunday Mirror that producers had been far from impressed with Charlotte when they had met with her about becoming a judge.

“She met producers at the beginning of the year but it was a very brief chat and they decided not to progress things,” the insider said.

“It was clear straightaway that she wasn’t right. She was, quite frankly, boring and she was never high on the priority list as there were far bigger names producers were looking at.”

However the singer’s manager has denied this, telling the paper: “I find this quite surprising as I was at the meeting with Charlotte.

“The X Factor team chatted with her in depth and said that they’d love her to be one of the judges. Charlotte agreed to get back to them as they were keen to move quickly.

“We later instructed Charlotte’s TV agent to inform X Factor she wasn’t interested in working with them.”

The judges are currently presiding over the boot camp stage of the show in London after learning which categories they will be mentoring.

Louis Walsh has been installed as the favourite to win the series in his final year on the panel after being given the boys, while Nicole Scherzinger has the boys, Sharon Osbourne the over 25s and Gary Barlow the groups.
