Ashley Tisdale played Sharpay Evans, co-president of the drama club at East High School (the school in "High School Musical") with her twin brother and was the closest thing the trio of films had to a villain. In real life, Tisdale maintains an ongoing musical career (her second album, "Guilty Pleasure," debuted at 12 on the Billboard charts in 2009) and acting career. She recently signed on as the costar of the CW drama series "Hellcats," which premieres in September.
