'Big Bang' Blowup! Kaley Cuoco Creating Chaos With Her Costars

Kaley Cuoco is the most unpopular cast member on Big Bang Theory since her personal life took over the tabloids — and the actress' drama is creating havoc behind the scenes, RadarOnline.com has exclusively learned.

"She's become the Jennifer Aniston of the show in that she is getting a ridiculous amount of attention in the press for her high-profile divorce," from Ryan Sweeting, revealed an insider.

The drama blowing up over 30-year-old Cuoco's splashy new romance with Karl Cook is only alienating her even more from costars Johnny Galecki and Jim Parsons, who definitely don't have her back.

"It used to be Kaley and Johnny versus Jim," noted the insider, "but now it's kind of everybody versus Kaley."

"In the last year there were times where Kaley was on big magazine covers but had only six lines in that week's episode," explained the insider of how Cuoco is getting buzz for all the wrong reasons. "There's a lot of resentment towards her."

"She has the cushiest job on the planet" compared to Jim, Johnny and even Melissa Rauch and Mayam Bialik, who pulls in a measly $100,000 per episode compared to Cuoco's $1 million payday, added the insider.

Unfortunately, there's not much her fellow stars can do to fix the tense situation.

"There's a lot of talk about how the ratings would go way down if she was pushed out," noted the source. "This isn't like the Friends or Seinfeld casts, who all stuck together. There has been a ton of jealousy and too many rifts over the years."
