There are few teen characters who epitomize the cut-throat world of every high school popularity contest quite like Regina George. She was the undisputed queen of North Shore High whose loyal followers looked to her with equal parts terror and admiration. It was the breakout role for actress Rachel McAdams, who was actually 26 when she portrayed the iconic teen character. The very same year, the beauty would star in yet another feature film hit, The Notebook, alongside heartthrob Ryan Gosling.
