Are The Big Bang Theory's Mayim Bialik And Kaley Cuoco Friends In Real Life?

At its heart, "The Big Bang Theory" is about friendship. That may seem counterintuitive for a show about socially awkward nerds, but that's the point. Even among people like Sheldon Cooper, friendship is an important part of daily life, something that is shown multiple times over the course of the series. Among these examples, the friendship between Penny (Kaley Cuoco) and Amy (Mayim Bialik) certainly stands out. Though the two had a tenuous time getting to know each other when Amy was first introduced in Season 3, by the end of the series, they are as thick as thieves despite their differences.

However, the actors who play them might not be as chummy as they are on the show. For years, rumors have swirled regarding a possible on-set feud between them. Gossip websites such as Radar Online have used terms like "catfight" to describe the conflict, which allegedly got so bad that the two had to be separated. Unfortunately for celebrity drama lovers, however, there's not much credence to these claims. In fact, it'd be fair to say that Mayim Bialik and Kaley Cuoco share a solid friendship in real life.

Despite the rumors, Cuoco and Bialik are friends

Truthfully, the best thing one can say about the rumors of the feud between Kaley Cuoco and Mayim Bialik is that they're entertaining and at least somewhat believable. It's not overly strange for cast members on a long-running series to develop a sense of animosity, especially when money is involved. This happens to be the cause of the rumor, which supposedly surrounds the massive pay gap between original and later cast members (via Geeks). More specifically, the rumors claim that Bialik made $100,000 an episode, while Cuoco made $1,000,000 and that Bialik did not like it.

However, many of the articles that discuss these rumors have no real sources to back up their claims. Meanwhile, articles that discuss Cuoco and Bialik's friendship have sources that are much more credible. According to Variety, Cuoco and her other original co-stars all took pay cuts in 2017 to increase the paychecks of both Bialik and Bernadette actor Melissa Rauch, though Cuoco and others still made much more at the end of the day.

Regardless of the pay gap between the two, however, it's clear that they're friends. When Cuoco got married to her now ex-husband Karl Cook in 2018, Bialik was one of the few "Big Bang Theory" cast members to actually attend (via TV Insider). Based on that alone, it's clear that the two are closer than rumors would have one believe.
