"Big Bang Theory" actress Kaley Cuoco has reportedly been warring not just with a co-star, but with the entire cast already.

Could there be truth to this allegation? What could be the reason behind it? Does the rumored disparity of her salary from what the others have been receiving have something to do with it?

A new report hinted that the alleged animosity between the 30-year-old actress and her co-stars wa brought about by her romance with Karl Cook.

"It used to be Kaley and Johnny versus Jim," an insider reportedly dished to Radar Online about "Big Bag Theory" star Kaley Cuoco, "but now it's kind of everybody versus Kaley." Unfortunately, as alleged by the report, there is nothing that the other stars can do to address the tension.

The unnamed source reportedly pointed out that Cuoco appeared to have been getting the buzz for "all the wrong reasons."

"In the last year there were times where Kaley was on big magazine covers but had only six lines in that week's episode," the source explained. "There's a lot of resentment towards her."

With her job being described as the "cushiest" on the planet especially when compared to the roles of Johnny Galecki, Jim Parsons, Melissa Rauch, and Mayam Bialik, "Big Bang Theory" star Kaley Cuoco has been reportedly getting $1 million payday, way higher than the others' rumored salary of $100,000 per episode.

However, amid this strong speculation, Gossip Cop shared that there is no truth to the Radar Online report.

"Kaley Cuoco is not creating 'chaos' on the set of 'The Big Bang Theory' nor is she 'unpopular' with her co-stars, despite a new report," the entertainment site said. "Gossip Cop can exclusively correct the record. We're told the claim is completely 'ridiculous.'"
