Naya Rivera, Now
Gleeks’ favorite mean girl, Santana gives Sue a run for her money in the one-liner department. In the first season, Santana relished her promiscuous reputation and her ability to make her classmates cower with a glare or a harsh word. In season 2, it was revealed that Santana was a lesbian, and Rivera's nuanced performance really brought Santana's struggles to light in an honest and touching way. Now, her and Brittany are married and super happy.
