Simon Cowell and ITV are reportedly clashing over the future of The X Factor, and Gary Barlow's spot on the panel.
It's been widely reported over the past year that X Factor boss Simon wasn't keen on Gary joining the show, but was overruled by ITV chiefs who had the final say.
With ratings declining, Simon is once again keen to try and get rid of Gary, as well as make other changes to the format.
Sion apparently wants to take the show "back to basics", ditching the huge arena auditions as well as revamping the judging panel, for what will be the third time in as many years.
But ITV are said to be "furious" about the plans, with the Daily Express claiming the channel is worried that the show could lose Take That star Gary in the shake up.
A supposed "senior ITV insider" told the newspaper today: “To say we are unhappy with Syco briefing about changes would be an understatement – bosses here are furious.
“We appreciate something needs to be done to shore up the show, but talks haven’t taken place yet – we’ve only just finished the series for goodness sake. Talks will begin in the New Year, but suggestions we have decided what changes will be made, or that we have already lined up a replacement for Gary, are completely untrue."
The source added: “It’s no secret we think a great deal of Gary. He was our choice to replace Simon two years ago, and we have big plans to work with him in the coming years – either on or off X Factor.”
X Factor's chief executive producer Richard Holloway said today that every aspect of next year's tenth series will be analysed in a bit to make it "amazing".
He told the Guardian about the early plans: "It's our 10th anniversary in 2013, and we want it to be amazing.
"It's about who the judges will be next year. Do we reformat the show? Do we introduce a new element?"
