'Big Bang' Feud! Kaley Cuoco Blasted For Making More Money Than Her Costars!

The 30-year-old actress brings in $1 million per episode for The Big Bang Theory with costars Johnny Galecki and Jim Parsons, but Mayim Bialik only brings in $100,000 per episode!

The Blossom star confessed that the entire cast is "ALL overpaid," but that didn't sit well with the 8 Simple Rules star.

“Kaley is furious at Mayim for trash-talking her earnings,” a source told RadarOnline. “She thinks it’s just a case of sour grapes and jealousy.”

Mayim, 40, told the New York Daily News that she is "just grateful to be employed."

“I don’t make as much money as people think I do,” she explained to the publication.

“I don’t think the pay has anything to do with the quality of the show,” she concluded. “We have an extraordinary cast and amazing writing staff and people all care passionately about putting on a show every week.”
