Calista Flockhart
Remember this star from Ally McBeal? Calista Flockhart was always performing, even as early as cheering for Shawnee High School in her hometown of New Jersey. Then, she graduated and attended the Mason Gross School of the Arts at Rutgers University where her career really started to gain traction.
Michael Douglas
Up until the 1950s, cheerleading was actually a predominantly male sport. Choate Preparatory School was where this Douglas learned to cheer, chant, tumble, and stunt as well as the rest of them. When he was cast in the Marvel films as scientist Hank Pym, he joined another male cheerleader... Paul Rudd!
