'X Factor' bosses are on a collision course with ITV - as the planned wage bill for the new judges tops 6 million pounds, reports thesun.co.uk. Sharon Osbourne, set to return after six years, is on course for between 1.5 million and 2 million pounds. Gary Barlow is looking to boost his 1.5 million pounds after agreeing to come back following talks with Simon Cowell.

Nicole Scherzinger is holding out for a similar deal to Gary's, plus benefits, including flying her own stylist and make-up team over from the US. Louis Walsh, who has a 1 million pounds deal, has been told he will be back. Last year's panel - who often tell singers: 'You made that song your own' - cost a lot less. Tulisa Contostavlos earned a reported 450,000 pounds, while Nicole got 750,000 pounds.
