Kaley Cuoco popped up in an Instagram video posted by "The Kelly Clarkson Show" this week. The 34-year-old actress who became a household name thanks to her role as Penny on "The Big Bang Theory" is set to star in her new "The Flight Attendant" series, but the video showing Kaley with Kelly Clarkson on the series' couch was solidly focused on all things "Big Bang."
In fact, the video appeared to bring out a confession from Kaley. Namely, that the actress sometimes doesn't even recognize herself when watching old reruns of herself on-screen.
