Sally Field
You might recognize this celeb from her work in Forest Gump or Mrs. Doubtfire, but she was performing long before that. This star was a cheer team member at Birmingham High School in Van Nuys, California. Later on, though, she would be a star known for shows like The Flying Nun and Gidget.
Fergie
Born as Stacie Ann Ferguson, Fergie was a beloved member of her high school cheer team for her sunny attitude and pretty face. She also defied the stereotype that cheerleaders are dumb, considering she was a straight-A student at Glen A. Wilson High School. She later went on to join the Black Eyed Peas.
