Dannii Minogue and Louis Walsh have reportedly been ordered to reapply for their own X Factor judging jobs.

With Simon Cowell and the majority of the X Factor production crew in America, a new team has been brought in to oversee the UK version with Dannii and Louis being told they have to apply again and attend an interview if they want to be part of the eighth series.

According to the Daily Mirror, the pair, who are said to be ’embarrassed and frustrated’ have also been asked to come up with new ideas for the ITV1 show.

An insider said: “Simon wants them both back on the panel because he loves the chemistry the pair has developed.

“The fact he has ordered them to reaudition and screen-test for their jobs is something of a formality – both are assured of the position.

“However, it is still pretty galling and to have to go through the motions of explaining why they would be good for the role, and what they could bring to the position, is extremely frustrating.

“But Simon is determined to avoid complacency this series and wants all the judges to be at the top of their game.

“They are two of the most sought-after jobs in the industry so it’s only fair they apply for their places just like anybody else.

“During the application process, the duo will answer questions about mistakes they made in previous shows and in what ways they would approach mentoring in 2011 – things to help freshen up this series, making it bigger and better than ever.

The move is especially frustrating for Dannii, who triumphed in last year’s contest with Matt Cardle.

The source added: “Dannii especially is pretty embarrassed about the whole charade.”
