Former "Big Bang Theory" star Kaley Cuoco is one of the biggest TV stars around but she was clearly starstruck when meeting actress, Catherine O'Hara. Cuoco met up with the "Schitt's Creek" star this week and immediately took to Instagram to share the moment with her millions of fans. The 35-year-old star of "The Flight Attendant" made it clear O'Hara is one of her comedic inspirations and legends, which definitely makes sense looking back on Cuoco's own impressive run in comedy.
