'X Factor' bosses were given a headache before Saturday night's show after a row broke out between the rejects from past series over who should sing what during their group number.
Kitty Brucknell, Rylan Clark, Diva Fever, Wagner and Johnny Robinson all reportedly had various demands ahead of their performance.
According to The Sun, Kitty was left in floods of tears and Diva Fever and Johnny threatened to pull out unless they were given a solo.
Producers eventually agreed after they held up rehearsals for hours - but had the last laugh when they turned down their mics and hardly featured them on screen.
A source told The Sun: “Talk about divas - this lot were worse than anyone we’ve ever dealt with.
“But the reality is they were just there as window dressing. People wanted to see Wagner and Rylan not Diva bloody Fever.
“They held things up so long that The Killers and Tom Odell had to sound check while people were taking their seats.”
Sam Bailey went on to win the tenth series of 'The X Factor' after scoring more than one million viewer votes.
