'Big Bang Theory' Tension Explodes: Cast 'Jealous As Hell' Of $27M Star Jim Parsons!

They may play best buddies on screen, but behind the scenes, the cast of The Big Bang Theory is battling over one star’s big bucks!

Jim Parsons, who plays know-it-all Sheldon Cooper on the show, banks a whopping $27.5 million a year, making him TV’s highest paid star. And it makes his co-stars extremely envious, an insider told RadarOnline.com.

Kaley Cuoco and Johnny Galecki are “jealous as hell” of Parsons, a source claimed, with Galecki especially “silently simmering” as he feels overshadowed.

“They all used to pal around when the show first started, but not anymore,” the insider alleged. “Now they are at each other’s throats.”

Earlier this year, Parsons added to his growing bank account by serving as the narrator for Big Bang spinoff Young Sheldon. Meanwhile, as RadarOnline.com reported, Cuoco and Galecki, who play lovers Penny and Leonard on the show, are growing increasingly upset as they are left behind.

“It’s no secret Kaley thinks of herself as the show’s big draw,” spilled one insider.

As tensions rise, ratings for the one-time hit continue to plummet, reaching an all-time low earlier this season. The stars, who each bank over a million dollars per episode, are now eyeing other projects.

“Everyone’s moving in different directions these days,” said a source. “It’s no longer a tight-knit group.”
