Simon Cowell rows with Louis
Simon Cowell and Louis Walsh have fallen out after Simon accused Louis of not looking after his 'X Factor' acts
Simon Cowell and Louis Walsh had a furious row backstage at 'The X Factor' this weekend.
The two judges were reportedly involved in an angry clash after the music mogul warned his fellow panellist - who mentors the over 28s group - to spend more time looking after his acts and taking more care with their song productions.
An insider on the ITV show told the Daily Mirror newspaper: "The pair were at war. There was a lot of effing and blinding. They were really going for each other.
"Simon is furious with Louis for spending so little time backstage with his acts. To make matters worse, he was accused of choosing dull and unoriginal songs for them. Simon was insisting that the other judges go all-out with exciting track choices and original choreography and styling."
After Louis shocked viewers by slating Simon's handling of girl group Belle Amie on air during Saturday's (23.10.10) show, Simon got his own back on Sunday (24.10.10) by axing the Irish mentor's act John Adeleye and blaming the judge for his decision.
He told the care assistant: "I just don't think you've been looked after properly."
Now contestants are said to be worried that they could become victims of their mentors' bitter feud.
An insider said: "Backstage the contestants are baffled - saying they don't know whether they've done something wrong or whether their mentor has."
