Kaley Cuoco – 35 Years Old

We can’t think of any actress that perfectly portrays Penny’s role in the hit sitcom The Big Bang Theory other than Kaley Cuoco. The actress dominated the small screen from 2007 to 2019, playing the beautiful Cheesecake factory waitress’s role, who was loved by many. This role alone made the now-35-year-old star one of the highest-paid actresses in 2018, earning nearly $25 million from the show.

The series didn’t only make Kaley rich, but it also opened a lot of doors for her acting career. She went on to do several TV and movie projects year after year. When it ended, Kaley ended up having her own TV series, Flight Attendant, on HBO Max. She also has a new movie coming, The Man from Toronto, which is now in post-production. Kaley gave credits to the iconic TV sitcom for making her a big star in the industry.
