Jayma Mays
Though she's Emma Pillsbury, a high school guidance counselor on Glee, Jayma was actually a high school cheerleader back in the day. She and her squad members are seen here donning blue and yellow while happily supporting their school mascot, the Wolves. That smile would light up a crowd!
Brooke Shields
Brooke Shields is famously one of the world's most beautiful women. Whether she was posing for the camera or acting in Emmeline in the 1980s The Blue Lagoon, she did it all with a smile. That career-defining grin was one she learned from her spirited cheer squad at her private high school in New Jersey.
