Kirstie Alley
Alley cheered for Wichita Southeast High School in Kansas before she got her big break. She also had way shorter hair at the time, which was unusual for a cheerleader. It must have helped her character though because soon after high school she was cast on the show Cheers.
Kendall Jenner
She might be the most famous woman in the world today, but only a few years ago, she was an awkward teen. The Kardashian sister Kendall Jenner got some relief from the limelight in school. She is seen here sporting a blue and white uniform as a cheer team member for her high school.
