Dianna Elise Agron (/ˈeɪɡrɒn/; born April 30, 1986) is an American actress, singer, and dancer. In 2006, Agron made her television debut as Jessica Grant on CSI: NY. From 2006 to 2007, Agron had recurring roles on Veronica Mars as Jenny Budosh, and Heroes as Debbie Marshall. When she was 15, she found out that her father had multiple sclerosis. In an interview for Cosmopolitan, she revealed, "Quite a bit changed after that. At that age, you don't see mortality in your parents." The disease caused her parents' relationship to fall apart, and they decided to separate, which was devastating for her and her younger brother. She stated, "I had to play therapist to my family... be the glue. Those kinds of things I'm not ready to speak about yet." In 2009, Agron was cast as Quinn Fabray on the Fox musical comedy-drama series Glee. Agron has appeared in the films The Hunters (2011), I Am Number Four (2011), The Family (2013), Zipper (2015), Bare (2015), and Novitiate (2017).
