Glee - Agron Fires Manager And Agent

The blonde beauty found fame last year (09) with her portrayal of cheerleader Quinn Fabray on the hit series and she's since starred in a number of films, including Burlesque alongside Cher and Christina Aguilera.

But she's said to have been unhappy with the guidance of manager Lena Roklin and her representatives at the Gersh Agency, and has now switched to top talent firm the William Morris Endeavor company.

A source tells New York Post's gossip column PageSix, "She is delighted with the success of Glee and her role. But she parted ways with them around a month ago. Dianna has been working as an actress since she was a child, she is smart and has a strong grasp on where her career is going."
