Dianna Agron

A triple-threat performer with a beauty-queen smile, Dianna Agron first gained notoriety as the mean-girl cheerleader who gets taught a lesson by Claire Bennet (Hayden Panettiere) on NBC's cult hit "Heroes" (2006-2010). A talented actress, singer and dancer, Agron became a household name with yet another mean-girl cheerleader - this time as Quinn Fabray, the conflicted head Cheerio and celibacy club leader who finds herself pregnant on creator Ryan Murphy's breakout musical drama hit, "Glee" (Fox, 2009-15). Able to finally showcase her full range of talents on the popular program, Agron captured the hearts of audiences, bringing a more touching, human side to the resident high school beauty queen than usually shown onscreen. Exhibiting versatility and vulnerability, Agron proved why she was more than just a fresh pretty face.
