Jessie J, Willl.i.am, Tom Jones and Danny O'Donoghue are reportedly getting as much as £500,000 for their work on the new music reality series, over five times the £90,000 that the Strictly stars get.
According to The Sun, Bruno, Len and Craig are unhappy with the cash being spent on the new show.
"There are some rumblings of discontent over what they see as the huge sums being spent on The Voice," an insider told the newspaper.
The tabloid claims that Will.i.am will be getting £500k, Tom Jones £300k, Jessie J £200k and Danny £100k.
There's good news for the Strictly ballroom experts though, who will be getting more cash this year to make sure they stay with the show, which lost Alesha Dixon in January.
The singer deflected to ITV1 for Britain's Got Talent, where she's not getting paid over three times her £100,000 Strictly fee.
A BBC source said: "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."
The Voice UK launches on March 24.
