'Strictly Come Dancing' judges are furious after learning 'The Voice' panel are being paid much more.
Dance experts Len Goodman, Craig Revel Horwood and Bruno Tonioli are said to have asked for a pay rise after learning their current £90,000-a-series deals on the BBC One show are dwarfed by the salaries of Danny O'Donoghue, Jessie J, Sir Tom Jones and will.i.am - whose fees range from £100,000 to £500,000.
A source said: "There are some rumblings of discontent over what they see as the huge sums being spent on 'The Voice'."
While insiders claim the differing sums are justified as the coaches on 'The Voice' were already household names, the 'Strictly' panel are unlikely to be disappointed when they begin contract negotiations later this month.
A source told The Sun newspaper: "When they come to renegotiate their contracts the BBC will bear in mind that last year's series was one of the best ever - and their new deals will reflect that and they will be paid accordingly."
A BBC spokesman added: "The role of the judges on 'Strictly' is massively important to the show."
'Strictly' bosses are currently on the hunt for a new judge following the departure of Alesha Dixon, who quit to join ITV's 'Britain's Got Talent'.
