We guess bonding over their time as Disney darlings is out of the question.

Britney Spears and Demi Lovato are reportedly at odds over on the set of  the ‘X Factor,’ and it’s gotten so bad, they can’t even stand each other anymore.

“Tensions are at the boiling point,” said a show insider to Star. “There is a bitter rivalry between them, and it’s already pretty much exploded — which is crazy considering how early into filming it is.”

“Demi thinks Britney is a twit, and Britney thinks Demi is beneath her,” said another source. “They avoid each other as much as possible when the cameras aren’t rolling.”

Uh yea, ya think? We guess it’s kind of a no brainer that two big singers in the industry would get on one another’s nerves every now and then. We know if we were in the same room with any kind of competition whatsoever, we’d be pulling our hair back and removing our hoop earrings.

But since Demi’s rehab stay and Britney turning over a new leaf since… that year we refuse to talk about, we have a hard time believing these two actually hate each other that much.
