Kaley Cuoco Reveals She Almost Wasn't Cast on 'Big Bang Theory'

Kaley Cuoco was this close to not being on The Big Bang Theory!

During a recent interview promoting the last few episodes of the hit comedy series, the 33-year-old actress revealed that when she first auditioned for the role of Penny she didn’t get it because producers thought she was too young.

“I didn’t get [the original role called Katie] the first time around,” Kaley shared via Cinema Blend. “I was too young, which I love saying because I don’t get to say that I’m too young anymore. Then, a year later, I heard they were doing it again, and they brought me back in to read for Penny.”

When the show first premiered back in 2007, Kaley was only 22-years-old.

The Big Bang Theory will end with an hour-long episode on CBS on Thursday, May 16.
