The three main stars of "The Big Bang Theory" - Jim Parsons, Kaley Cuoco and Johnny Galecki - have finally worked out new deals for Season 8 of the CBS sitcom. According to Deadline, Parsons and his two lead costars signed new contracts over the weekend and will get a reported $1 million per episode.

The contracts extend for three years and covers Seasons 8 through 10. There is also a possibility for an 11th Season. Deadline reports that the stars' new contracts go beyond per-episode fees and also includes signing bonuses, back-end advances and production deals.

"In addition to tripling their most recent salaries of $350,000 an episode... Parsons, Galecki and Cuoco also quadrupled their previous ownership on the show, which has gone up from 0.25 to more than a point," Deadline wrote. "Parson's pact includes a production deal that spans TV and features and possibly theater."

Cuoco and Galecki's new deals also include "producing arrangements." Throughout the three years of the new contracts, Parsons, Galecki and Cuoco are slated to earn around $90 million, with some people saying it could be closer to $100 million.

Mayim Bialik and Melissa Rauch have already signed new contracts which included significant raises. The only cast members left to work out new deals is Simon Helberg and Kunal Nayyar. The two have been working together to settle their new contracts and are hoping to close the salary gap with Parsons, Galecki and Cuoco, Deadline reports.

Back in 2010, Helberg and Nayyar signed deals to get paid $100,000 an episode. Production for Season 8 of "The Big Bang Theory" was supposed to begin last week and premieres Monday, Sept. 22.
