The Voice US judge Christina Aguilera is reportedly "furious" at bosses allegedly offering Blake Shelton and Gwen Stefani "huge bonuses" to flaunt their relationship.

The Beautiful singer - who has returned to the talent show after a one season hiatus - is said to be unhappy with the deal offered to the couple.

Stefani will be joining Shelton as a mentor on Team Blake, and Radar Online reports that they will be offered incentives for loved up moments like on air duets.

Blake and Christina are both on the panel

Gwen will be a mentor for her man's team

"Producers want the two of them to give fans a full-on love-fest this season when she is a mentor on Team Blake, and they are going to throw in huge bonuses for exclusives, such as on-air duets, engagements, etc," a source said.

"Christina is furious... [She] wants Gwen out of the picture and is already throwing mini tantrums about it.

"She said that Gwen is 'not vocally talented' and would not be on the show at all anymore if it was not for her relationship with Blake."
