Dianna Agron has appeared on television shows such as Shark, Close to Home, CSI: NY, Numb3rs and a recurring role on Veronica Mars. She then appeared as Harper on a 13 episode series of short films called It's a Mall World, directed by Milo Ventimiglia, and airing on MTV, and then on the second season of Heroes, also with Ventimiglia.
Agron's most notable role to date is likely as Quinn Fabray, a high school cheerleader, on the FOX series Glee, which has received high ratings and critical acclaim since the series began in September 2009.
It’s been an emotional roller coaster for the “Glee” cast as they prepare for their final farewell to their friend Cory Monteith, who unexpectedly passed away in July, but it appears Dianna Agron will not be making a special appearance during the tribute episode.
While interviewing with the New York Post, the former cast member announced she’s not certain she will be reprising her role as Cory’s former on-set girlfriend Quinn in the upcoming season.
