'The Voice' Christina Aguilera Diva Behavior? Are Adam Levine, Pharrell Williams, Blake Shelton Not Impressed by Xtina's Antics?

Christina Aguilera might have just made her triumphant return to The Voice this season, but according to new reports she is rubbing everyone the wrong way. While we are huge Xtina fans, it seems that the cast and crew of the NBC reality competition -- including Adam Levine, Blake Shelton and Pharrell Williams -- are not enjoying the return of the pop icon.

According to Radar Online, Christina has been extremely bossy on the set of the show and has allegedly been a terror to work with.

"She just has ridiculous demands since coming back as a judge, and everyone is wishing she did not return!" a source close to the show told the new site. "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."

Radar even went one step further to say that Levine and Xtina are always bickering with each other.

"To make matters worse, she is constantly fighting with Adam. They cannot stand each other," the insider explained.

The site is also reporting that Levine and Pharrell Williams have been at each other's throats lately because the Maroon 5 singer is jealous of his fellow coach.

We aren't so sure we are buying these rumors. After all, they seem like such a happy family during the episodes, so either the reports are false or they're just really good actors.

I mean, Adam even chose to be on Team Christina after singing a cover of Elton John's "Tiny Dancer," last week, according to the Los Angeles Times.

"All right, so now I gotta pick a coach," the singer explained to the audience after his performance. "I gotta go with my gut here. I gotta go with, uh ... Christina."

This was such a cute moment that we are calling a big old BS on the rumors that there is any tension going on behind the scenes.
