As The Big Bang Theory enters season 10, the focus has turned to the show’s future. Is the hit CBS sitcom and recent Poppy Award winner approaching the finish line or are there enough jokes to make about nerds to fill another season? For series star Kaley Cuoco, the question of an eleventh season comes down to one thing: money.

“It’s a very expensive question for a lot of people,” said Cuoco on Jimmy Kimmel Live Monday.

After Kimmel asked if she thought 10 seasons was enough, Cuoco nodded and said yes with a laugh. “It’s a lot of hair. That’s a lot of denim sizes,” said Cuoco, who joined the show when she was 21 years old. “I went from like hot to like 30 [years old].”

She added: “I just cannot believe how much we have all changed. The guys look exactly the same. I’m the only one that’s changed. They’ve worn the same t-shirts this entire time.”

For its part, CBS is definitely open to more Big Bang Theory, which is one of the highest rated shows on TV. “We are very confident that everyone involved wants more Big Bang past year 10,” said CBS chief Glenn Geller at the Television Critics Association’s press tour in August. “We’ll put it on as long as everyone wants Big Bang on the air. I hope it lasts forever.”

The Big Bang Theory returns Monday, Sept. 19 at 8 p.m. ET on CBS.
