The battle on NBC's Season Eight of The Voice is not just between the contestants. After learning that judges Adam Levine and Pharrell Williams are at each other's throats, RadarOnline.com has exclusively learned that returning judge Christina Aguilera has production staff reeling over her on-set diva antics.
"She just has ridiculous demands since coming back as a judge, and everyone is wishing she did not return!" a show insider tells Radar.
According to the source, "Christina is such a terror to work with. She is frequently late and she doesn't even seem to care or apologize for holding up the filming of the show."
"To make matters worse, she is constantly fighting with Adam. They cannot stand each other."
Although the 34-year-old "Fighter" is a veteran judge, she took off for the last two seasons of the show to have a child with husband Matthew Rutler and was replaced by Shakira and Gwen Stefani.
Now, the source says, "Everyone really misses Shakira and Gwen. NBC was actually hoping to keep one of the girls so that they would have two female and two male judges, but Christina said absolutely not, and that she would be the only female judge or she would not do it at all."
"Since Christina brings in the ratings, she feels that she owns the place and can demand whatever she wants," the source explains. "She has even called it her show!"
