"The Big Bang Theory" already has controversy among Kaley Cuoco (Penny), Jim Parsons (Sheldon Copper) and Bernadette Rostenkowski (Melissa Rauch) and Howard Wolowitz (Simon Helberg). However, despite the controversy, rumors are rife in the air that the show might carry on beyond season 10.

In addition, speculations suggested that Cuoco and Johnny Galecki will be leaving the show. The buzz about the two lead characters leaving stemmed from the fact that their contracts are set to expire after season 10.

According to several rumor there are no plans from renewing the contract on CBS and Warner Bros' ends.

In March, Cuoco told TVLine that she is more than willing to reprise her role in the future seasons of "Big Bang Theory." In fact, she hinted that she would be on the show for as long as it takes.

"I think it's a given that we want to be here. That's the overall consensus. It might be a sticky road, but if I have anything to do with it, we'd be here for much longer. That's the goal," Cuoco said.

The executive producer of the show also mentioned last December that he had some ideas on how to end the show perfectly.

"I can't speak to the future or on behalf of the cast or where we'll be then but it's certainly possible that it could go past that," Molaro told The Hollywood Reporter.

"The reality is that maybe season 10 is the ending point. The real answer is I don't know and all I can do right now is go episode to episode and try to make each one the best that we can," he went on.

"Big Bang Theory" season 10 is set to premiere on Oct. 14 on CBS.
