Naya Rivera — She might play a sometimes conniving Cheerios cheerleader on TV, but when she was in high school, she was allegedly a huge nerd. Naya said, “In high school, I was most like Artie and Rachel. I knew what I wanted, like Rachel, although I wasn’t as obnoxious. But like Artie, I was a nerd, always trying to fit in and get my hair to lie flat.”
