Reese Witherspoon
Back in the day, this Legally Blonde star was on top of the world, and on top of the pyramid. The Walk the Line celebrity was part of her school's cheerleading squad long before fame came into her life. Here she is in a throwback photo posted by Reese herself, cheering on the Generals.
Ann Margret
Born in Sweden in 1941, Anne was an accomplished singer, spry dancer, and peppy cheerleader for New Trier High School in Winnetka, Illinois. She happily smiled for the cameras and the crowds even before she was famous. The starlet went on to act in pictures like Bye Bye Birdie, Carnal Knowledge, Grumpy Old Men, and The Cheap Detective.
