The Voice 2014 producers are apparently 'disappointed' Leah McFall is returning for the battle rounds.
Leah was the runner up on last year's show and this series has seen Will.i.am invite her back to inspire his latest crop of singers for the weekend's battle rounds.
Once again Will will also joined by original member of the Black Eyed Peas Dante Santiago, who has now appeared on every series so far, to help him train his acts ahead of the next stage.
But show bosses are said to be a bit underwhelmed by the selection of guest mentors by Will.
A supposed insider told the Daily Star newspaper today: “It’s the time when we hope to add even more star appeal by getting big name artists to help the coaches.
"We were disappointed that Will picked Leah.”
That said the other coaches' choices aren't exactly huge names.
Kylie Minogue will be getting help from Scissor Sisters star Jake Shears, Ricky Wilson's acts will get advice from Katy B while Sir Tom Jones is joined by apparent pal Tinie Tempah.
In the battles, the coaches will have to pitch their acts against one another in a series of head to head musical battles.
The coaches will give the artists a song that they must duet on before mentoring both competitors both together and separately ahead of the performance.
One winner will be declared in each pairing leaving six acts in each team but there's an extra twist again this year with the Steals.
Each coach will be able to add a seventh act to their team by selecting one of the singers that their rivals has rejected.
