Cuoco grew up with fellow actress Ashley Tisdale, who asked Cuoco to be her date to her high school prom.
A devoted equestrian, Cuoco was involved in a serious riding accident on September 13, 2010, crushing several bones in her left leg. She missed two episodes of "The Big Bang Theory" and spent most of the rest of the season hidden behind a bar on the show's restaurant set to hide her cast.
